Abstract: A macerating and aspiration tool for removing blood masses from the brain.

Abstract: An electronic tester with digital, and analog, and memory test circuitry on a single platform. A test head is coupled to a device under test. The device under test can be a system-on-a-chip integrated circuit, a mixed signal integrated circuit, a digital integrated circuit, or an analog integrated circuit. Digital test circuitry applies digital test signals to the device under test coupled to the test head and receives digital outputs from the device under test in response to the digital test signals. Analog test circuitry applies analog test signals to the device under test coupled to the test head and receives analog outputs from the device under test in response to the analog test signals. Memory test circuitry applies memory test patterns to the device under test coupled to the test head and receives memory outputs from the device under test in response to the memory test patterns.

Abstract: The invention presents a sled device for testing the rollover threshold of a vehicle. The sled has a carriage that is mounted on a track. The carriage can slide upon the track from a first track location. The carriage is configured so that an actual vehicle may be placed on the carriage. When a vehicle is on the carriage, the vehicle is positioned with one side of the vehicle positioned toward the first tract location and the second side of the vehicle positioned toward the second track location. The carriage is propelled from the first tract location to the second track location by an accelerator. As the carriage nears the second track location, a decelerator slows and arrests the movement of the carriage, thereby simulating an impulse potentially sufficient to cause the vehicle to roll.

Abstract: A feedback device providing immediate feedback to a user. The feedback device includes a main hollow tubular body having a first transmitter end and an opposite second receiver end. The feedback device is “C” shaped and sized to comfortably allow the user to hold the transmitter end close to his mouth while simultaneously positioning the receiver end close to the ear of the user. The user speaks into the transmitter end. The sounds emitted by the user are amplified within the main tubular body and directed through the receiver end to the ear of the user. The feedback device provides immediate feedback for all sounds produced by the user. The feedback device may be used to enhance the reading and speaking ability of the user.

Abstract: A communications headset includes a headset enclosure and a receiver enclosure coupled thereto by various means allowing displacement of the receiver enclosure with respect to the headset enclosure at any of a variety of angles, rotations, and distances. The adaptable positioning of the receiver enclosure allows the headset to be used by a wide variety of users having different ear shapes and sizes, while providing a stable, comfortable fit and ensuring good acoustic performance. In one embodiment the receiver enclosure is slidably coupled to a ball tube having a ball that rests in a socket of the headset enclosure. The receiver enclosure can telescope along the length of the ball tube and can rotate about an axis of the tube. The ball can be rotated in the socket to position the receiver enclosure at any of a variety of angles relative to the headset enclosure. A voice transmitter is also coupled to the headset enclosure so as to allow adjustment of length, angular position, and rotation.

Abstract: A tool for recontouring metal such as dents in the body of an automobile, for use in conjunction with an electrical welding apparatus, including a shaft on which a weight reciprocates, the weight being permitted to selectively collide with structure provided by the shaft to impart a force to the shaft along the longitudinal axis thereof, a portion of the shaft being electrically conductive and electrically connected to the electrical welding apparatus, the electrically conductive portion of the shaft for contacting the metal surface to be straightened, activation of the electrical welding apparatus welding the electrically conductive portion of the shaft to the surface to be straightened so that the forces transferred to the shaft by the weight can act upon the surface to be straightened.
