The city plans to use state grant funding to pay local law enforcement officers overtime to enforce the regulations.The package will limit the speed of dockless scooters from 15 mph to 8 mph in high-traffic areas like Spanish Landing, near Petco Park and boardwalks in the city’s beach communities, and as low as 3 mph along the Embarcadero and the Martin Luther King Jr. Promenade.“At the end of the day this is a good starting point” said City Councilman Scott Sherman. “It’s not going to be where we end up. … The fact that both sides probably aren’t totally happy with what is happening here today means we probably have a fairly good deal somewhere in the middle.”Scooter companies like Bird, Lime and Razor will be required to use geofencing technology on their scooters to limit speeds and parking abilities in designated areas around the city. Lime and Bird already use geofencing to reduce scooter speeds in areas like the Santa Monica Beach Bike Path.The city has begun to designate 330 scooter parking zones along city streets so as to decrease the number of scooters parked on sidewalks. In downtown, scooter riders and companies will only be able to park devices in groups of four, with at least 40 feet between groups.Many of the package’s supporters were representatives of Bird, Lime, Razor and Jump, a dockless bicycle and scooter company owned by the ride-booking company Uber. The San Diego Regional Chamber of Commerce and public transit advocacy group Circulate San Diego also endorsed the ordinance.“We look forward to a continued partnership and to regulations that advance our shared objectives of making the city even more livable by reducing car usage, traffic and carbon emissions,” said Bird spokeswoman Kyndell Gaglio.Most opponents of the package favored an outright ban of dockless transit devices throughout the city, let alone on the city’s sidewalks. City Councilwoman Jennifer Campbell said she’d be one such opponent had she been on the council when they first arrived in San Diego early last year.“I have a call to action to these companies that own these devices,” Campbell said. “If they successfully obtain a permit, you must do your part to keep our residents safe with rider education and accountability and I will be watching.”Campbell and City Councilwoman Barbara Bry said they would support a future ban on riding dockless scooters along boardwalks in the city’s beach neighborhoods, which city officials may draft in the coming weeks and months along with other changes to facets of the ordinance like which areas are designated 3 mph and 8 mph zones.Some opponents also suggested that the council is responsible for residents’ injuries and deaths due to scooter-related incidents.The regulations include a provision indemnifying the city for scooter-related accidents and injuries. The scooter companies will also be required to maintain liability insurance of up to $2 million per accident and $4 million aggregate.The city will require that scooter companies obtain a six-month operational permit with a $5,141 fee and pay $150 per scooter or bike each year to continue operating in San Diego. According to the city, revenue from the per-device fee will be added to the city’s general fund to be used for scooter safety outreach, law enforcement and various transportation infrastructure improvements.Companies can renew permits only in January or July, at which time they will have a chance to negotiate operating terms like fleet size, which they are not currently required to report to the city. Companies could also add a special event provision to their operating permit to increase fleet size by 20 percent for 10 days per year for $15 per scooter, per day.Mayor Kevin Faulconer first proposed a regulatory framework for dockless scooters and bikes in October.The council’s Active Transportation and Infrastructure Committee unanimously approved the full regulatory package in February and requested that it return to the committee within six months of its implementation for further review and to ensure the city is keeping pace with the evolution of technologies like geofencing.“The way people get around town has changed quite a bit and we’re embracing that by putting in place common-sense rules to protect the quality of life in our neighborhoods,” Faulconer said in a statement. “These new regulations allow us to hold these companies accountable for their actions while establishing clear rules of the road to ensure this evolving industry grows in a safe and responsible way.”The council must vote on the ordinance a second time for it to take effect. A date has not been set for the second vote. April 24, 2019
Citation: Entanglement on demand (2008, April 7) retrieved 18 August 2019 from https://phys.org/news/2008-04-entanglement-demand.html One of the problems in quantum information processing is inefficiency. Photon entanglement is generally considered a leading candidate for quantum computing (it is used for teleportation and cryptography), but right now it is sort of a hit and miss proposition. “The only methods we have for generating entangled photons are random,” Yosi Avron tells PhysOrg.com. “You don’t always get an entangled pair, and when you do, after you test the photons, they are useless.” This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Avron, a physicist at the Technion-Israel Institute of Technology, believes that he and his colleagues may have found a technique that could solve this problem of photon entanglement. Avron worked with Gershoni, Bisker, Lindner and Meirom at Technion-Israel, as well as Warburton at Heriot-Watt University in Edinburgh. The team’s scheme revolves around time reordering, and is explained in Physical Review Letters: “Entanglement on Demand through Time Reordering.”“The key is something called switch path ambiguity,” explains Avron. He points out that in quantum mechanics, a particle can be in two places at once. “If you have two slits on a paper, and you send a photon toward them, the photon can go through both at once. It doesn’t have to choose. If you have a screen behind these two slits, the interference pattern that shows is the same behind each slit. The photon went through both.”Avron goes on to explain that the key is in setting up different paths for the photons to follow, and in creating a situation in which two states give the same result. In that way, it would be possible to produced entangled photons on demand, rather than using hit and miss:“If you have a system with an atom, you start it in an excited state. Then it relaxes and releases a photon at an intermediate state. Then it relaxes more and releases a photon at the ground state. The ambiguity comes in when we create a second intermediate state, identical to the first, so that you have a state where two photons are generated in alternative ways.”It sounds nice, but Avron acknowledges that this where more problems arise. “It is difficult to get two states that are precisely identical like that,” he says. “The states have slightly different energies and this adversely affects entanglement.” The solution the team came up with was to re-arrange the timing of the system. “This is not a new idea,” he qualifies, “but we were the first to create a believable theory of how it could be done.” “All we have to do is reorder one of the paths,” Avron explains. “And if you do, then you could get a situation where you get entanglement because the states become identical…Instead of matching in each generation of photons, it is possible to match across generations and reorder them. Quantum mechanics allows for this without penalty.”Avron is careful to point out that at this stage the results are theoretical. “But,” he continues, “we think that it is possible to design an experiment to test it. David Gershoni is working on such an experiment.”The experiment may take one or two years to get done, but Avron is confident of the results. “It has been difficult to get high quality entanglement on demand,” he explains, “and what we have discovered is that it is possible and something that we can do in a few years’ time.”Copyright 2007 PhysOrg.com.

German city to test viability of inductive charging system on two real bus lines More information: www.tosa2013.com/en#/tosa2013 (Phys.org) —A new type of battery bus system being tested in Switzerland is able to operate continually by making use of flash-charging stations. Called Trolleybus Optimisation Systeme Alimentation (TOSA), the new bus and recharging system is currently being tested on a one mile route in Geneva between the city’s airport and international exhibition center. © 2013 Phys.org The system is designed to allow for quickly “topping off” batteries at bus stops, with a longer charge of just three to four minutes between bus runs. Buses are equipped with a laser controlled arm that sits atop the bus and automatically guides the contact mechanism to its mate in an overhanging charging station. Passengers get on and off the bus just as they would any other bus.The system was designed by Zurich based electronics giant ABB with assistance from Geneva Public Transport and other city agencies. The TOSA system flash charges at a rate of 400 kW, allowing batteries to be topped off in just 15 seconds every few stops. Officials describing the system call it a truly zero-carbon emission system because the electricity to recharge the buses is generated using hydroelectricity. They noted also that such a bus system would be a big improvement over conventional electric buses that get their power from overhead lines and also other battery run buses that must be taken out of service periodically for recharging. They claim also that despite such frequent recharging, the batteries in the buses are expected to last for at least a decade. The TOSA system, two years in the making, was designed to be used in areas of heavy congestion, where ridership would be high—the test bus is 19 meters long and can hold 135 passengers. The test run of the system is designed to highlight potential problems with the system to allow for improvements to be made. Once that happens, ABB plans to sell the system to other cities around the world—that could mean the end of loud diesel buses spewing smoke or overhead electrical lines cluttering the view from the street. ABB also says that its system is more cost-effective than other mass transportation systems and more flexible as well because it allows for different types of designs for the charging stations.
