Abstract: Using a common reference address when processing calls between a native application binary interface (ABI) and a foreign ABI. Based on a caller calling using a reference address, a lookup structure is used to determine whether the reference address is within a memory range storing native code and that the callee is native, or a memory range not storing native code and that the callee is foreign. Execution of a callee is initiated based on one of (i) calling the callee using the reference address within an emulator when the caller is native and the callee is foreign; (ii) calling an entry thunk when the caller is foreign and the callee is native; (iii) calling an exit thunk when the caller is native and the callee is foreign; or (iv) directly calling the callee using the reference address when the caller is native and the callee is native.

Abstract: Various electric balance vehicles are described. In some embodiments, the vehicle has first and second housings with platforms to support a user's feet. The first and second housings can be rotatable relative to each other. The vehicle can have first and second wheel assemblies. A support member can extend within tapered portions of the first and second housings. In some embodiments, one of the first and second housings can rotate relative to the support member and the other of the housings can be rotationally fixed relative to the support member. The vehicle can balance and provide locomotion to the user. The vehicle can be light, compact, and/or have a low center of gravity.

Abstract: A marking device that is supported by a personal mobility vehicle, such as a scooter, is movable from a first position, in which the marking device does not contact the riding surface, and a second position, in which the marking device contacts the riding surface. The marking device includes an attachment portion and a marking portion that creates markings on the riding surface as a result of frictional contact with the riding surface. The marking device can also include an actuation portion which is accessible to the user and allows the user to move the marking device to the second position. In one arrangement, the marking device includes an elastic marking member which is configured to bend in order to maintain contact with the riding surface.

Abstract: Various powered mobility systems for users are described. The powered mobility system can include at least one powered skate. The powered skate can include a platform, a plurality of wheels, and a motor assembly. The motor assembly can include a motor. The motor can be powered by a power supply. A motor control can be implemented to determine when power is supplied to the motor from the power supply.

Abstract: An electric powered personal mobility vehicle that includes at least one front wheel and an electric motor that provides rotational force to a wheel of the vehicle. The electric motor is supported by the vehicle and is powered by a rechargeable battery that is also supported by the vehicle. The vehicle can also include swivel caster wheels each configured to rotate about a wheel axis.

Abstract: A personal mobility vehicle, such as a scooter, includes at least one battery and motor for powering at least one driven wheel. The vehicle also includes a braking assembly configured to isolate the motor from the at least one driven wheel such that power is terminated from the motor to the at least one wheel in response to a user engaging a braking assembly of the vehicle. The vehicle can include a switch or position sensor that interacts with the braking assembly to initiate the isolation of the motor from the at least one driven wheel and the switch or position sensor preferably is inaccessible to the foot of the user.

Abstract: A variety of scooters are disclosed. In some embodiments, a scooter can include a pivot assembly that allows the scooter to move between a folded and unfolded configuration. The pivot assembly can include a knob that frees a pin from a bracket to allow the scooter to fold. Turing the knob increases compressive forces on elements of the pivot assembly to reduce rattling noise and wobbling movement when the scooter is in use. Some embodiments of the scooter can include a center stand that can be deployed from either side of the scooter deck to stabilize the scooter when the scooter is stationary. Certain embodiments have an ergonomic handgrip.

Abstract: Systems and methods for obtaining images of a lunar surface and cislunar space using a hybrid telescope are provided. One hybrid telescope is carried by each of two spacecraft. Each spacecraft is in an elliptical orbit about the Moon. The periapsides of the spacecraft orbits are 180° apart from one another. In addition, the spacecraft can be phased 180° apart from one another to enable an offset in access times of each telescope to the cislunar and surface domains respectively. The image sensors associated with the telescopes can include a staring mode for collecting images from cislunar space, and a scanning mode for collecting images from the lunar surface.
