摘要： A modular neon sign control system with a plurality of discrete neon letters, numbers or symbols, each with plugs to plug into at any place along a continuous electrical rail. Each neon letter, etc. is a single tube having its own driving inverter and digital decoder. Dip switches set a unique digital code into the decoder for each letter. A programmed memory controls a system encoder which sends coded signals to each decoder to compare with each letter's unique code. Those letters receiving the matching digital signals are activated or deactivated according to the program. The letters, etc. of the sign can be operated simultaneously, serially, randomly, in a pattern, or in a flashing manner. Power from an ac adapter is supplied along with the signals from the encoder to the electrical rail, and the decoder separates the power from the coded signals. The letters may be individually and easily prearranged and substituted in a sign.

摘要： A ventricular assistive device (VAD) based on a progressive cavity pump includes a pump housing having an inlet and an outlet, a pump stator contained within the pump housing, a pump rotor rotatably disposed within the pump stator, a motor including a motor rotor contained within the pump housing and a direct drive means connected between the motor rotor and an axial shaft of the pump rotor for rotating the pump rotor. The motor rotates the motor rotor, which in turn rotates the pump rotor through the direct drive means. The rotation of the pump rotor within the pump stator forms a plurality of cavities that carry blood forward through the pump housing from the inlet to the outlet as the motor drives the direct drive means.

摘要： A lightweight hand-held scanning device for repetitively scanning a laser light source having a laser light generating means and at least one high speed scanning motor controlled by a resonant motor circuit which automatically controls the frequency and amplitude of oscillation of a high speed scanning motor. The frequency and amplitude control is accomplished by using a single feedback signal obtained from the windings of the motor which indicates resonance and which also measures the amplitude of oscillation. The feedback signal obtained is a second harmonic of the driving current. The circuit can be utilized to tune and maintain the motor in a resonant oscillating mode. By controlling both the frequency and amplitude of oscillation the high speed scanning motor can maintain a consistent scanning speed and use less power.

摘要： A system includes a communication module that receives a request to post content to an event gallery associated with an event. The request in turn includes geo-location data for a device sending the content, and identification data identifying the device or a user of the device. The system further has an event gallery module to perform a first authorization operation that includes determining that the geo-location data corresponds to a geo-location fence associated with an event. The event gallery module also performs a second authorization operation that includes using the identification data to verify an attribute of the user. Finally, based on the first and second authorization operations, the event gallery module may selectively authorize the device to post the content to the event gallery.

摘要： A rotor driven linear flow blood pump (LFBP) which completely separates the driving motor from the pumped blood is used as a vascular assist device (VAD). Without the possible hazard of blood contamination, a brushless d. c. motor (BLDC) is ideal to drive and to control the LFBP. Thus we have the best of two worlds: For patient mobility, d. c. batteries are the best as a VAD energy source, and LFBP provides the most means at a physician's disposal for curing his patient with a severely damaged heart. A key to success in making the above possible is a new concept of surface affinity. Complete blood containment is made possible by using a material with zero surface affinity with blood as the bearing material throughout.
