Patent number: 5542112Abstract: A method of reliably transmitting signalling tones employs a radio communication unit suitable for encoding (303) data packets. The radio has a processor (101) for processing a first signal, which processing is incompatible for use with signalling tones. The radio further includes an input device (110) for providing signals when asserted. In a preferred embodiment, when the processor (101) is enabled to process the first signal, and a user does not assert the input device (110), the radio transmits the processed first signal. On the other hand, when the processor (101) is enabled, and the user asserts the input device (110), the radio transmits (304) repeated data packets, for the duration of the assertion, which identify a particular signalling tone.Type: GrantFiled: April 11, 1995Date of Patent: July 30, 1996Inventors: Leopold Alonso, Timothy J.

Patent number: 5533673Abstract: A nozzle system for imparting compound motion, including an orbital component and a rotational component, to the discharged fluid. The nozzle system comprises a specially engineered shell surrounding a freely flexible hose of sufficient structural integrity to simultaneously exhibit two different motion characteristics to impart the compound motion to the discharged fluid. When fluid is delivered to the nozzle system, the hose moves orbitally; that is, the hose rides against the wall of the shell in a cork screwing manner. Simultaneously, the hose rotates or twists back and forth about its own axis relative to its fixed end. Both components of motion are imparted to the discharged fluid to enhance spray power and expanse.Type: GrantFiled: October 31, 1994Date of Patent: July 9, 1996Assignee: Jet Blast Products Corp.Inventors: Timothy J.

Patent number: 5477550Abstract: Within a transmitter (101), a quantity of data (201) to be transmitted is parsed into variable length, uniquely identified messages (202), which are in turn parsed into fixed-length, uniquely identified blocks (207-211). Messages are buffered and then transmitted to a receiver (103). Upon reception of a message-received communication by the transmitter (101) corresponding to a particular buffered message, that particular message is unbuffered. Upon reception of a message-partially-received communication by the transmitter (101) corresponding to a particular buffered message, those blocks corresponding to portions of the particular buffered message that were not adequately received (703) are retransmitted.Type: GrantFiled: March 8, 1993Date of Patent: December 19, 1995Inventors: Kenneth J. Crisler, Michael L. Needham, Timothy J. Wilson

Patent number: 5471670Abstract: In a multiple site communication system, a method for determining when to hand off a communication that is occurring on one communication resource to another communication resource may be accomplished in the following manner. Once a communication unit is allocated a communication resource, it begins to monitor signal usabilities of the allocated communication resource and a predetermined set of alternate communication resources. A broadcast unit associated with the allocated communication resource also monitors the signal usability of the allocated communication resource. When the signal usability of the allocated communication resource is determined to be unfavorable by the communication unit or the broadcast unit, one of the alternate communication resources is selected based on calculated signal usability, such that the communication unit can continue the communication.Type: GrantFiled: July 2, 1993Date of Patent: November 28, 1995Assignee: Motorola, Inc.Inventors: Garry C. Hess, Barry S. Leung, Timothy J. Wilson
