Abstract: A rivet gun system includes a rivet gun frame having two ends. A die is coupled to one end, and a force sensor coupled to the rivet gun frame. The force sensor detects force applied to the die and generates a force signal in response to the force. A holding coil defines a channel within the rivet gun frame and generates an electromagnetic force along the channel. The channel includes an end defined by an end stop and an end defined by the die. A main coil further defines the channel between the holding coil and the die. The main coil also generates an electromagnetic force along the channel. A plunger slides through the channel in response to the electromagnetic forces. A force sensor electronics controller receives the force signal from the force sensor and activates the holding coil and the main coil in response to the force signal above an activation threshold.

Abstract: The present invention describes a human presenilin-interacting protein, ubiquilin, that modulates presenilin protein levels and is associated with neuropathological lesions such as neurofibrillary tangles and Lewy bodies in Alzheimer's disease and Parkinson's disease affected brains. Also, the present invention relates to anti-ubiquilin antibodies that prominently stain neurons. The present invention further relates to introducing and expressing ubiquilin to modulate cell functions relating to presenilin synthesis.

Abstract: Olfactory neuron cultures and methods of making and using the same are disclosed. The olfactory neuron cultures may be used to study oxidative stress-related disorders and diseases such as Alzheimer's disease. The olfactory neuron cultures may be used to screen candidate compounds for those which reduce, inhibit or prevent oxidative stress or damage. The compounds which reduce, inhibit or prevent oxidative stress or damage may be used to treat Alzheimer's disease and other oxidative stress-related disorders and diseases.

Abstract: A shaft assembly and method of manufacture are provided. A molded member is attached to the shaft. An axially extending groove is provided in the shaft, the groove having a bottom and a pair of radially projecting sides. A member is molded onto the shaft. A portion of the member flows into the groove and engages the groove sides, thereby fixing the member to the shaft.

Abstract: An electronically commutated brushless DC motor primarily for fractional horsepower applications of the type where at any instant one motor winding is unpowered and used to detect back EMF zero-crossings which information is used to initiate winding commutations. The duration of the pulse produced in this winding due to dissipation of stored energy by free-wheel diodes in parallel with the commutation devices after supply of current has been removed from this winding is used to provide a measure of motor current. This allows for simplified commutation device current limiting circuits and is available for control purposes which are a function of motor torque. There is also disclosed a method for maximizing useful power output by reducing the phase angle between the motor current and the back EMF. This is accomplished by introducing a delay in commutating the motor windings beyond the occurrence of each back EMF zero-crossing, with the delay being a function of the time between commutations.

Abstract: A portable fire extinguisher composed of a portable air tank with a pressure regulator and a liquid carrying tank containing the fire extinguishing liquid. A support bracket carries the liquid carrying tank, and a pair of shoulder straps connecting the support bracket and air tank allow the extinguisher to be carried on the users shoulders. A flexible hose directs the pressure regulated air to the top of the liquid tank. A trigger operated spray nozzle connected to the bottom of the liquid tank by a flexible hose allows the dispersal of a controlled spray of fire extinguishing liquid.
