Patent CA-2192513-A1 (CA)
Title: Automated Wireless-Call Completion Using a Paging Network
Inventor: GAULKE DAVID ALAN
IPC: H04B7/26
Filed: 1996-12-10
Abstract: In a cellular telephone system (FIG. 1), a pager (122) is associated with a cellular phone (121) that is normally kept turned off and thus not drawing power from its battery (513). When an incoming call for the cellular phone arrives at a cellular exchange (103) and the exchange determines that the cellular phone is not registered with a base station (107-109), a paging system (105) is caused to transmit an incoming-call-indicative paging signal to the pager. Receipt of this paging signal at the pager either causes the user of the pager and the cellular phone to turn on the cellular phone, or causes the pager to turn on the cellular phone automatically via associated circuitry (502, 515). Activation causes the cellular phone to register with a base station, whereupon the cellular exchange extends the incoming call to thecellular phone through that base station. If the incoming call is not answered, or when the incoming call is completed, the paging system is caused to transmit a second paging signal to the pager. Receipt of the second paging signal at the pager leads to the cellular phone being turned off again. The cellular phone can therefore normally be turned off without fear of missing incoming calls. Battery power of the cellular phone is thus conserved.

Patent CA-2215882-A1 (CA)
Inventor: MAIELLO DENNIS R
IPC: F23N1/02
Filed: 1997-09-16
Abstract: A modulating, forced draft, fuel-fired air heating furnace is provided with a two-speed draft inducer fan, and a fuel valve which is fully modulatable between a maximum firing rate and a low firing rate of approximately forty percent thereof. Incorporated into the furnace control system are normally closed low and high fire pressure-electric switches which sense and are sequentially closed by increasingly negative pressure in the draft inducer fan. Upon a call for heat from a thermostat located in the conditioned space served by the furnace, the draft inducer fan is energized at its high speed setting, and a signal is sent to the fuel valve to set it at its full firing rate flow when opened by an ignition switch portion of the control system. The control system functions to open the fuel valve at this maximum flow setting, and permit light-off of the burner, only if (1) both of the low and high fire pressure-electric switches are closed, and (2) thedraft inducer fan is operating at its high speed setting. In this manner, in addition to providing a wide range of furnace heating output modulation, reliable burner ignition is facilitated and heat exchanger warm-up corrosion is reduced due to the full firing rate start-up of the furnace. Moreover, the incorporation of the two-speed draft inducer fan substantially improves the overall fuel efficiency of the furnace.

Title: Combinational therapeutic methods employing nitric oxide scavengers and compositions useful therefor
Inventor: LAI CHING-SAN
IPC: A61K31/00
Filed: 1997-03-05
Abstract: In accordance with the present invention, there are provided combinational therapeutic methods for the in vivo inactivation or inhibition of formation (either directly or indirectly) of species which induce the expression of nitric oxide synthase, as well as reducing nitric oxide levels produced as a result of .NO synthase expression. In contrast to the inhibitory approach described in the prior art (i.e., wherein the function of the enzymes responsible for nitric oxide production is inhibited), the present invention employs a combination of inactivation (or inhibition) and scavenging approach whereby the stimulus of nitric oxide synthase expression is inactivated, or the production thereof is inhibited, and overproduced nitric oxide is bound in vivo to a suitable nitric oxide scavenger. The resulting complexes render the stimulus of nitric oxide synthase expression inactive (or inhibit the production thereof), and nitric oxide harmless. The resulting complexes are eventually excreted in the urine of the host. In another aspect, the present invention relates to reducing elevated nitric oxide levels associated with infectious and/or inflammatory conditions (and the treatment thereof), employing a combinational therapeutic method wherein an agent for the treatment of the infectious and/or inflammatory condition is coadministered along with a dithiocarbamate compound as a scavenger of overproduced nitric oxide. Further in accordance with the present invention, there are provided compositions and fomulations useful for carrying out the above-described methods.

Title: Novel techniques for the cancellation of beam squint in planar printed reflectors
Inventor: ITTIPIBOON APISAK
IPC: H01Q3/36
Filed: 1998-05-22
Abstract: Due to the frequency dependence of phasing mechanisms applied in planar printed reflectors, when using planar printed reflector antennas beam squint occurs as the frequency is scanned within the operating band. In order to reduce or eliminate beam squint, a n incident signal incident upon a reflector is altered in such a way that the outgoing signal retains a same direction. In an embodiment, this is achieved by providing feed elements in different locations, each feed element for feeding a signal of a different frequency. In another embodiment, two reflector arrays are used wherein beam squint caused by the first reflector array is compensated for by the second reflector array.
