Inventor: ANDRES JOHN
IPC: G08B17/00
Filed: 2001-08-10
Granted: 2010-06-22
Abstract: Presented is a communications protocol for use by interconnected hazardous condition detectors, such as smoke (12, 14) and carbon monoxide (16, 18) detectors for use in dwellings and other structures. This communications protocol provides conventional signaling to indicate the presence of a smoke condition necessitating the generation of a smoke temporal pattern by all interconnected detectors. The protocol further defines a signaling method by which conventional smoke detectors (12) that are incapable of providing temporal patterns other than that required for a smoke alarm condition will not be sent into an alarm mode of operation upon receipt of a signal other than the conventional smoke alarm signal. Through the use of an 8 bit alarm signal, multiple hazardous conditions may be signaled as well as operating modes such as test, hush, reset, low battery, etc. Also presented are smoke, carbon monoxide, and combination hazardous condition detectors that utilize the communications protocol presented herein.

Abstract: An electronic HEMD determines the optimum balance between gas cooling and heat exchanger pressure loss, for any given operating condition, and adjusts the gas flow rate through the exchanger accordingly, to yield the maximum net power savings (and thereby energy savings) afforded by the exchanger. Maintaining the optimum balance between cooling and exchanger pressure loss reduces the amount of energy required to transport a given volume of gas through a pipeline and thereby increases the transmission efficiency of the gas pipeline system. A method of operating a heat exchanger on a natural gas transmission pipeline using a control algorithm that in turn controls the position of a heat exchanger bypass valve. The current operating conditions of the upstream compressor and gas cooling system are continually monitored for any changes and the control algorithm determines, the optimum flow through the heat exchanger and initiates a command signal to the exchanger bypass valve operator to move the bypass valve and thereby increase or decrease the gas flow rate through the exchanger, as required, until the optimum balance between gas cooling and heat exchanger pressure loss has been achieved.

Granted: 2012-11-27
Abstract: It is problematic that communication by friendly communications systems (1) are jammed if they are located within the physical range of a friendly jammer (10) and within the frequency range covered by the jammer (10). The solution foresees that time windows are used for communications and transmissions between the participants ( 1.1, 1.2, 1.3 ) of the friendly communications system (1). These windows are established in advance within the communications system in accordance with a specification from the jammer (10) or created or matched individually for the short term by software. Since only the participants (1.1, 1.2, 1.3) that are communicating with each other know or identify these time windows it is only they who transmit or receive the information that corresponds to these time windows. The information is compressed in the manner and way that is known so that it can be transmitted and received completely in the brief duration of the time window. This information can then be decompressed and read out in the similarly known manner and way when jamming is in progress.
