Patent number: 5588025Abstract: A digital information receiver having a single oscillator providing a clock signal to the receiver circuitry. The receiver contains, in addition to the oscillator, an input signal processor, a symbol timing loop, a demodulator, a transport decoder, a transport timing loop, one or more applications decoders and a presentation device. The input signal processor digitizes an input signal and resamples the input signal using an interpolator such that the input signal is optimally sampled. The resampling is controlled by a symbol timing loop. In a first embodiment, the transport timing loop controls the frequency of the oscillator using transmitter timing information contained in the received signal. In a second embodiment, the oscillator is a free running oscillator and the transport timing loop controls a numerically controlled counter that, in turn, controls presentation timing of the information carried by the information in the input signal.Type: GrantFiled: March 15, 1995Date of Patent: December 24, 1996Assignee: David Sarnoff Research Center, Inc.Inventors: Christopher H.

Patent number: 5581720Abstract: In a computer for executing a computer program, apparatus and a method for updating information within a computer program instruction without interrupting execution of the computer program. The apparatus contains a memory for storing the information within the instruction at an address within the memory, circuitry for periodically accessing the information for execution by the computer, and circuitry for altering, between periodic accesses to the memory by the accessing circuitry, the information stored in the memory. In this manner, computer program execution is not interrupted to alter the information within the instruction. Typically, the information is a data field value contained within a computer microcode instruction. Consequently, the data field value is updated, but other information within the instruction such as an operational code (OPcode), is not altered by the update operation.Type: GrantFiled: March 10, 1995Date of Patent: December 3, 1996Assignee: David Sarnoff Research Center, Inc.Inventor: James T.

Patent number: 5570534Abstract: A fishing jig is disclosed for holding a fishing rod and moving the rod in an up and down motion in an oscillating manner. The rod is oscillated by an electric motor that drives a jigging wheel and lever arrangement via a gear assembly which is connected to the jigging wheel. Both the rate of oscillation and oscillation stroke may be varied. Upon a strike by a fish, the jig has a mechanism for quickly raising the rod in an upward direction with sufficient force to set the hook. The distance that the rod travels to set the hook also may be adjusted. In addition, the sensitivity of the jig can be adjusted with regard to both the amount of force that must be exerted upon the fishing rod holder as a result of a fish strike and the degree of travel which the rod holder must undergo, as a result of a fish strike to activate the hook set mechanism. The jig may also be coupled to an alarm that indicates activation of the hook set mechanism.Type: GrantFiled: June 6, 1995Date of Patent: November 5, 1996Assignees: Michael R. Bowen, David N.
