Title: Runt packet filter
Inventor: JENSEN GORDON A
IPC: H04L1/00
Filed: 1986-11-13
Granted: 1991-01-08
Abstract: Abstract Provided is a circuit for preventing local area network packets shorter than a predetermined bit length from being received by a local area network coprocessor.  Serial data which would otherwise be received by the coprocessor is delayed by a data-shift register of predetermined bit length.  Simultaneously, a carrier-sense-signal, which alerts the coprocessor that serial data is ready to be received, is modified by a carrier-sense-signal regeneration circuit.  If the carrier-sense-signal is detected true by the regeneration circuit for a number of clock cycles equal to the number of bits in the data-shift register, then the carrier-sense-signal is delivered to the coprocessor and the data in the data-shift register is received by the coprocessor.  Once the carrier-sense-signal goes false, the regeneration circuit continues to deliver the carrier-sense-signal until the data-shift register empties.

Abstract: ELECTRONIC IMAGING APPARATUS AND METHOD     ABSTRACT OF THE DISCLOSURE         An electronic imaging system includes an optical system for imaging radiation from a scene onto the image sensing surface of an imaging device for a selected sample period.  The imaging device may take the form of a two dimensional array of photoresponsive areas having a device specific upper spatial frequency limit.  In order to eliminate alias signal components in the output video signal caused by spatial frequency components in the scene radiation greater than the Nyquist spatial frequency of the device, the optical system is designed to have a spatial frequency limit no higher than the Nyquist frequency of the imaging device and thus functions as a low pass optical filter. The spatial frequency response of the optical components can be controlled by controlling the rotationally sym-metric aberrations, and in the preferred form, higher order terms, third and above, which contribute to the spherical aberration of a lens system are designed to have balancing non-zero values to provide the necessary characteristics of the modulation transfer function of the optical system.

Granted: 1994-03-08
Abstract: ABSTRACT OF THE DISCLOSURE            In a method and a device for the widespread fine-bubble aeration of liquids, resilient, perforated membranes, which are preferably in the form of aeration hoses, are arranged in a liquid receptacle and are maintained horizontal by means of holding and guiding devices and are stretched, relative to their rest states, preferably by means of tensioning devices. Because of the stretching, the passage of the gas is improved and a uniform, finely dispersed gas bubble formation is produced. For clearing the perforated membranes of blockages of the perforations, the stretched state of the membranes is briefly released and subsequently again reproduced. For strong impurities, the gas supply is interrupted, the membranes are exhausted of gas and water, the stretched state is subsequently released and, after a predetermined time, gas is again fed into the perforated membranes and then the stretched state is reproduced.
