Patent CA-2251025-C (CA)
Inventor: SAYEGH SOHEIL
IPC: H04B7/185
Filed: 1997-04-10
Granted: 2001-11-27
Abstract: In a satellite communication system including mobile communication devices, in which each of the mobile communication devices is associated with one of a plurality of subgroups, a method is provided for allocating those devices. According to the method, each of the groups of mobile communication devices is first partitioned into subgroups, each of the subgroups having a queue associated therewith. Subsequently, each of the mobile communication devices is assigned to more than one subgroup having a queue corresponding thereto so as to reduce queuing delays associated with the satellite communication system. In another embodiment, a message to be received by one of the mobile communication devices is transferred to the shorter of the queues corresponding to those subgroups to which the mobile communication device has been assigned.

Abstract: A wireless base station has a transmitter and receiver. Transmission signals are applied to an antenna through a transmit bandpass filter that is tuned for a transmit band of frequencies. Received signals from the antenna are applied to the receiver through a receive bandpass filter that is tuned for a receive band of frequencies An RF switching array consisting of four RF switches interconnects the output of the transmitter and the input of the receiver such that normal, loopback (self-test), and scanning modes can be performed. In the normal mode, the antenna is connected to the transmitter and receiver through the transmit and receive bandpass filters, respectively. The transmit and signal paths are effectively isolated from each other by three serially-connected open switches. In the loopback mode, the transmitter output is connected to the receiver input. In the scanning mode, the antenna is connected to the receiver through the transmit bandpass filter. The same set of interconnects provides for loopback and normal operation as well as the new scanning operation. The use of switches rather than couplers or couplers for the loopback function reduces noise and crosstalk between transmit and receive signal lines and lower losses in these lines.

Title: Stable protein and nucleic acid formulations using non-aqueous, anhydrous, aprotic, hydrophobic, non-polar vehicles with low reactivity
Inventor: HUANG MANLEY T F
IPC: A61K38/00

Granted: 2008-11-25
Abstract: This invention relates to stable non-aqueous formulations which are suspensions of proteinaceous substances or nucleic acids in non-aqueous, anhydrous, aprotic, hydrophobic, non-polar vehicles with low reactivity. More specifically, the present invention relates to stable protein or nucleic acid formulations wherein the compound remains in stable, dry powder form, yet the formulation is flowable and, therefore amenable to delivery to an animal via injection, transdermal administration, oral delivery or using an implantable device for sustained delivery. These stable formulations may be stored at elevated temperatures (e.g., 37 °C) for long periods of time and are especially useful as flowable formulations which can be shipped and/or stored at high temperatures or in implantable delivery devices for long term delivery (e.g., 1-12 months or longer) of drug.

Abstract: Described is a method for providing secure transmission of information between at least two users of a telecommunications network, using a secret, random, binary key of great length that is used only once for purposes of encryption. This key is generated in a key generator (10), for example by means of an optical random generator with a beam splitter, and is preferably accessible to the public; this key is read onto at least two transportable data carriers (12), for example, CDs, and is then issued in this form to the users, each of which receives a data carrier (12) with the key read onto it. There is no additional storage of the key. The users then install this key carrier (12) into reading devices (14) that are associated with the telecommunications terminal devices (16), such as telephones, facsimile apparatuses, or PCs, that are being used by the users. When a connection is being set up, correct installation of the key and its matching are checked by logistics devices (18) that are each similarly associated with the telecommunications terminal devices (16); during encryption and decryption of the information that is to be transmitted, the logistics devices (19) check for synchronization of the keys or at least the part of said keys that has been input. A system for implementing this method with the devices required for this purpose is also described.

Title: Multi-port ram based cross-connect system
Inventor: LAVRANCHUK JAMES S
IPC: H04Q3/52
Filed: 1999-10-29
Granted: 2004-06-29
Abstract: A high capacity digital non-blocking cross-connect switching fabric is realized by employing a multi-port RAM based space-time switch having a plurality of write circuits and a plurality of read circuits, each of which operates at a timing rate that is a prescribed fraction of the input/output clock rate of the input/output ports of the multi-port RAM based cross-connect switching fabric. The at least one multi-port RAM switch unit has a plurality of write circuits and a plurality of read circuits, each of which operates at a timing rate that is a prescribed fraction of the input/output clock rate of the input/output ports of the multi-port RAM based cross-connect switching fabric. Additionally, in one embodiment, each of the write circuits and each of the read circuits has independent and unrestricted access to all data storage positions in each of a plurality of storage units that make up the at least one multi-port RAM switch unit. Because the write circuits and each of the read circuits are operating at the prescribed fraction of the multi-port RAM switch unit input/output clock rate, a multi-port RAM based cross-connect switching fabric is realizable which has a significantly larger storage capacity that is accessible within a reasonable access time. In one embodiment of the invention, a plurality of multi-port RAM switch units is employed to realize a multi-port RAM based non-blocking cross-connect switching fabric. In a specific embodiment, the fractional write rate is exploited so that a plurality of input ports can be served by a single write circuit. In another embodiment, each write circuit is assigned exclusive access to a particular segment of the write address space that is different from that assigned to any other write circuit. Furthermore, since the read circuits are operating at a fraction of the output port clock rate, each of the read circuits can serve a plurality of output ports by delivering read signal elements from the multi-port RAM switch unit to the output ports in a round robin fashion.  Additionally, in another embodiment of the invention, each read circuit is assigned exclusive access to a particular segment of the read address space that is different from that assigned to any other read circuit. Consequently, the capacity of the multi-port RAM based cross-connect switching fabric is markedly increased.
