Patent CA-2161814-C (CA)
Inventor: HARTLE JEFFREY E
IPC: A01C1/00
Filed: 1991-10-24
Granted: 1998-04-21
Abstract: Analogs   of  botanic   seed   are  disclosed. According to one embodiment, a seed analog comprises a unit of totipotent plant tissue disposed relative to a unit of non-phytotoxic hydrated gel that is "oxygenated," i.e.,  has a concentration of molecular oxygen that is higher than a concentration of molecular oxygen that would otherwise be absorbed from the atmosphere by the hydrated gel at standard temperature and pressure.  Gel oxygenation can  be  by  exposure  to  a  gas  having  an  enriched concentration of molecular oxygen relative to the earth's atmosphere or by including in the hydrated gel an oxygen-carrying  or  oxygen-absorbing  compound  such  as  a perfluorocarbon and/or silicone oil.  An outer shell can be included that, with the hydrated gel, forms a capsule enclosing the unit of totipotent plant tissue.  According to another embodiment, the seed analog includes a shoot restraint that is resistant to penetration by a growing shoot and/or cotyledons.  In such seed analogs, the unit of totipotent plant tissue has  a  shoot end,  and the restraint is disposed relative to the shoot so as to prevent,  during  germination  of  the  totipotent  plant tissue, entrapment of the shoot end in the seed analog. Also disclosed are corresponding methods for germinating totipotent  plant  tissue  and  for  manufacturing  seed analogs, all of which especially are useful for producing large numbers of genetically identical plants.

Abstract: Tetrahydrofurans, tetrahydrothiophenes, pyrrolidines and cyclopentanes are disclosed that reduce the chemotaxis and respiratory burst leading to the formation of damaging oxygen radicals of polymorphonuclear leukocytes during an inflammatory or immune response. The compounds exhibit this biological activity by acting as PAF receptor antagonists, by inhibiting the enzyme 5-lipoxygenase, or by exhibiting dual activity, i.e., by acting as both a PAF receptor antagonist and inhibitor of 5-lipoxygenase. It has been determined that 5-lipoxygenase activity, oral availability, and stability in vivo (for example, glucuronidation rate) can vary significantly among the optical isomers of the disclosed compounds.

Patent CA-2203917-C (CA)
Inventor: ASHLEY JAMES P
IPC: H04Q7/20
Filed: 1996-09-04
Granted: 2000-06-27
Abstract: A noise suppression system (109) implemented in communication system (700) provides an improved update decision during instances of sudden increase in background noise level. The noise suppression system (109), inter alia, generates an update by continually monitoring the deviation of spectral energy and forcing an update based on a predetermined threshold criterion. The spectral energy deviation is determined by utilizing an element which has the past values of the power spectral components exponentially weighted. The exponential weighting is a function of the current input energy, which means the higher the input signal energy, the longer the exponential window. Conversely, the lower the signal energy, the shorter the exponential window. The noise suppression system (109) also inhibits a forced update during periods of continuous, non-stationary input signals (such as "music-on-hold").

Filed: 1997-06-11
Granted: 2002-01-22
Abstract: A method and system are disclosed for a transmitter to maintain priority on a communication channel in a multiple wireless communication system environment.  An exemplary method for maintaining priority includes transmitting a priority signal to maintain priority for the transmitter on the communication channel.  The priority signal may be pseudo-random noise (PRN) signals. In one embodiment, the PRN signals are transmitted in response to activity sensed on the communication channel, one cause of which may be a contending transmitter transmitting on the communication channel. In this embodiment the step of transmitting is for a predetermined duration and causes the contending transmitter to stop transmitting on the communication channel. In an alternate embodiment, the transmission of the PRN signals is periodic and occurs sufficiently often to cause the contending transmitter to abstain from ever transmitting on the communication channel.
