  • Patent number: 12173549
    Abstract: A mechanical adaptation to a vehicle power window controls is provided that require less hand/finger coordination and less force to actuate, therefore becoming useful for persons with limited control of their hands (e.g., arthritis, muscular dystrophy, multiple sclerosis, cerebral palsy, and spinal cord injury, among others). A power window control includes four levers, one on each control switch. Two of the levers are long and the other two are shorter. The long levers are provided on the two switches further away from the user (which control the front and rear left side windows). The short levers are attached to the two switches closer to the user (which control the front and rear right side windows).

  • Publication number: 20240256711
    Abstract: In some implementations, the disclosed systems and methods can replace components descriptive of private real-world objects with generic components that obscure details of the private real-world objects, such as the objects' structure and semantic information. In some implementations, the disclosed systems and methods can convert image and/or sensor data into pose data that can be used by a recipient device to animate an avatar of the sender while the audio stream is being played.

  • Publication number: 20210236366
    Abstract: The invention provides a personal micro-climate system that reduces the energy requirement to keep a person cool by providing a personal air-conditioned space specially for bed-ridden patients. A dome is provided to create a personal space that just cools the area where the patient is at avoiding wasting energy in cooling the room's floor, ceiling, walls and empty space. The cooling system can be energized through solar power, deep cycle battery packs, small power plant or through a combination thereof. The system allows for the movement of an automatic or semi-automatic bed. A transparent cover is stretched over a frame structure to allow for maximum visibility from the inside out and vice versa. The system allows ease of opening an attendant window for patient care or to help a bedridden patient in an emergency. Breathing tubes, feeding tubes, IV lines, sensors and cables can be fed into the dome through openings between a mattress cover and the micro-climate dome.

  • Patent number: 10851943
    Abstract: A method and device for detecting and extracting a gaseous fluid contained in a closed loop operating on a Rankine cycle are provided. The loop includes a multiplicity of constituents with, successively, a circulation and compression pump for a working fluid, a heat exchanger associated with a hot source, an expansion machine, a cooling exchanger, a working fluid tank and circulation pipes connecting these constituents. The method and device measure the temperature (Tréelle) and the pressure (Préelle) of the working fluid at a point of the loop when this loop is at rest, and, as soon as the measured pressure (Préelle) exceeds a threshold value (Pliquide saturé) for a given ambient temperature (T), activate equipment for extracting the gaseous fluid in order to discharge it from the loop.

  • Patent number: 8104358
    Abstract: A high sensitivity strain sensor that utilizes a micro-scale cavity built in a multi-layer structure, with a pair of interdigitalized capacitor incorporated on one of the layers, is described in this document. The device's capacitance changes produced by unattended deformations of the cavity can be used to measure the associated strain without using any movable electrodes. The sensor can be remotely energized from a radio frequency wave sent by a reader antenna to construct a battery-free wireless instrument. Changes on the sensor's resonant frequency are remotely detected so that a strain level is measured from fluctuations in the received signal. This detection method provides a simple, reliable and sensitive technique to measure small strain changes down to the pico-scale. Materials with a highly strain-dependant permittivity are integrated in the sensor to enhance its sensitivity. The proposed sensor consists of a simple planar structure.

  • Patent number: 6227981
    Abstract: The present invention contemplates an improved ball ramp assembly that enables even the most severely handicapped bowler to guide and accelerate a bowling ball toward the intended bowling pins. The bowling ramp assembly includes a ramp having a ball guide defining a ball path along the ramp, a base coupled to a proximal end of the ramp for supporting the ramp, a ball release coupled to the ramp for selectively controlling travel of the ball along the ramp, and a positioning assembly coupled to the ramp for adjusting the orientation of the ramp. The ball release includes a ball stopping member that moves between a ball blocking position and a ball releasing position. The positioning assembly includes at least one motor coupled to the ramp and a wheel located at the distal end of the ramp. The ball release and positioning assembly are both controlled by switches which may be located remotely from the ramp.

  • Patent number: 6171198
    Abstract: A merry-go-round with a frame supported for rotation by a plurality of driven wheels, the merry-go-round having a space for a wheel chair and a space for a non-wheel chair bound person. Each separate space on the merry-go-round is associated with a respective crank assembly such that a person in that space can drive one of the driven wheels through a crank. A plurality of smaller wheels secured to the underside of the frame provide additional support for the merry-go-round. The person in the non-wheel chair bound space can stand on the frame, or in an alternate embodiment can sit on a chair. Because the merry-go-round has spaces for both wheel chairs and non-wheel chair bound people, both can use the merry-go-round at the same time.
