Abstract: Methods and systems for controlling the parking brakes of a vehicle are provided. The system comprises a first brake unit; a second brake unit; a third brake unit; a fourth brake unit; a first controller powered by a first power source; a second controller powered by a second power source and communicatively coupled to the first controller via a first and second communication link; and a third controller powered by the first power source and communicatively coupled to the first controller via a third communication link and to the second controller via a fourth communication link, wherein the second controller, based at least in part on a signal received from the first controller, operates the first brake unit and the fourth brake unit, and the third controller, based at least in part on the signal received from the first controller, operates the second brake unit and the third brake unit.

Abstract: Drivable vehicles, such as electric go-karts, for driving in a controlled environment are equipped with a camera, a display, and a processor for controlling images on the display. In one embodiment, the camera and display are in a single smartphone, with the camera lens facing opposite to the display. The smartphone is affixed to a safety helmet, or other headgear, so that the driver can simultaneously view the display screen while seeing the real world using peripheral vision. Overlaid on the displayed real world image is any type of artificial reality image, such as obstacles, robot combatants, simulated vehicles, etc. The AR image may be independently controlled by the smartphone processor and interacts with the driver, such as by reacting to getting shot by the driver or shooting at the driver. The AR image is 3-D rendered so its perspective and size realistically changes as the vehicle is driven.

Abstract: A food elevator for a toaster or grill comprising a pair of elongate rail members and one or more handles secured to the rail members to facilitate the insertion and removal of the elevator into a toaster or grill. The rail members have depending therefrom first and second compartments. The first and second compartments have at least partially enclosed side and bottom surfaces such that the first compartment is capable of receiving and holding therein a frankfurter and the second compartment is capable of receiving and holding therein a frankfurter bun. The first compartment is generally dimensioned to hold and retain therein a frankfurter in an orientation generally perpendicular to the rail members and the second compartment is generally dimensioned to hold and retain therein a frankfurter bun in an orientation generally perpendicular to the rail members.

Abstract: An electric appliance, for cooking meat and buns simultaneously, has chambers for holding the meat and buns vertically, heating the meat on both sides and heating the bun on at least one side. The meat may be contained in a novel cage. The bun chamber may have one or two perforated plates for controlling the amount of radiant heat from impinging on the bun, thus affecting whether the bun is warmed or toasted.

Abstract: An elevator for a toaster is disclosed which has a first portion for supporting one or more frankfurters generally side by side between an opposed pair of heating elements in the toaster. The elevator includes a second portion for supporting one or more buns one in each bun heating chamber each bun being adjacent to a single heating element. The frankfurters are heated on two sides where the buns are heated on only one side. The side by side orientation of the first portion is at right angles to an axis formed between two of the buns when the buns are supported in the bun heating chamber by the second portion. In another aspect of the invention a toaster is provided which includes a frankfurter heating chamber, at least one bun heating chamber, and at least one heating element interposed between the frankfurter heating chamber and the bun heating chamber. The heating element simultaneously heating both the frankfurter and the bun.

Abstract: A toaster for heating both a frankfurter and a frankfurter bun is disclosed. The toaster has a frankfurter heating chamber having associated first heating elements for heating at least two opposed surfaces of a frankfurter placed in said frankfurter heating chamber and at least one bun heating chamber having an associated second heating element for heating at least one surface of a bun placed in said bun heating chamber. The toaster includes an elevator having a first portion for supporting the frankfurter in the frankfurter heating chamber and a second portion for supporting the bun in the bun heating chamber. A connecting means connects the first portion to said second portion and permits a limited amount of play between said first and second portion. In one embodiment the connecting means includes a generally upside down U-shaped link bar.
