This invention relates to trolley current collectors and, more specifically, to an improved current collector for use at high speeds. Current collectors for vehicles powered from overhead wires have evolved over many years with various improvements to overcome problems involving ease of use, maintenance of electrical contact between the current collecting shoe and the overhead conductor and handling of the stresses imposed on the system under various operating conditions. As the speed requirements of the electrically powered vehicle increase, vibration and noise problems have become more severe, and the devices which were useful under operating circumstances of some years ago are no longer satisfactory. An important factor is the fundamental condition that the electrical conductor is not rigid. Rather, it is a wire, or a set of wires, which can flex and move within certain limits. Although the wire is braced and restrained in various ways, it can nevertheless oscillate and undergo complex sets of vibrations and other movements.

It’s a lovely day out, and you decide to go for a walk along the trolley tracks that crisscross your town. As you walk, you hear a trolley behind you, and you step away from the tracks. But as the trolley gets closer, you hear the sounds of panic — the five people on board are shouting for help. The trolley’s brakes have gone out, and it’s gathering speed. You find that you just happen to be standing next to a side track that veers into a sand pit, potentially providing safety for the trolley’s five passengers.
All you have to do is pull a hand lever to switch the tracks, and you’ll save the five people. Sounds easy, right? But there’s a problem.
The problem with the trolley problem
What should you do? A lot of people seem to think that solving this thorny dilemma is necessary before we allow self-driving cars onto our roads. How else will they be able to decide who lives or dies when their algorithms make split-second decisions? I can see how this happened.

Mid-Coast Trolley construction began in fall and service is anticipated to begin in late Freeways and arterials in the Mid-Coast Corridor are generally congested and traffic congestion is projected to increase as the region grows. Population in the entire corridor is forecasted to increase 19 percent and employment is forecasted to increase 12 percent by the year The Mid-Coast Trolley extension will expand transportation capacity in the corridor to accommodate existing and future travel demand, particularly for peak period commute trips.
The Mid-Coast Trolley project will provide an effective alternative to congested freeways and roadways for travelers and will reduce vehicle miles traveled. View a “flyover” of the Mid-Coast Trolley route.

The competition will welcome Lego enthusiasts of all ages to unlock their inner creativity. Event organizer Sherry Gazlin says that the event is a great opportunity for a family day out. Gazlin says the competition helps families bond by constructing something for the other competition and then seeing the works. The displays will be open to the public from p. Judges are always local, with a representative from Bricks4Kidz — an after-school Lego program — on the panel along with other Lego enthusiasts.

Self-driving cars hold out the promise of being safer than manually driven cars. Collisions are sometimes unavoidable. So self-driving cars need to be programmed for how they should respond to scenarios where collisions are highly likely or unavoidable. The accident-scenarios self-driving cars might face have recently been likened to the key examples and dilemmas associated with the trolley problem.
In this article, we critically examine this tempting analogy. We identify three important ways in which the ethics of accident-algorithms for self-driving cars and the philosophy of the trolley problem differ from each other. These concern: i the basic decision-making situation faced by those who decide how self-driving cars should be programmed to deal with accidents; ii moral and legal responsibility; and iii decision-making in the face of risks and uncertainty.
In discussing these three areas of disanalogy, we isolate and identify a number of basic issues and complexities that arise within the ethics of the programming of self-driving cars.

Ensuring the Required Electrotechnical Properties during Recycling of Worn Trolley Wire Abstract: The paper presents information about the level of production of copper contact wires for trams and trolleybuses, their electrotechnical and strength properties, the most common shapes of wires used in transport. These wires are worn during operation; the initial shape is reduced in cross section, which decreases from mm 2 or 85 mm 2 to 30 mm 2.
Recycling of the worn contact wire allows manufacturing copper wire of round and rectangular cross-section, which is in great demand in the tram and trolleybus depots. The technology of wire recycling consists of its rolling according to the rhomb-oval scheme and cold drawing with the drawing ratio of 1. Rolling of round section with a diameter of 5. Cold drawing allows making a round wire with a diameter of 1.
