Title: Flow control method for short message service-busy subscriber
Inventor: ASTROM BO ARNE VALDEMAR
IPC: H04M3/46
Filed: 1995-11-29
Abstract: A flow control system and method in a global system for mobile communication (GSM) mobile telephone system for short message service (SMS). The SMS enables short text messages to be sent to and from mobile stations. The system and method is directed to a control for a service for messages sent to MSs (MT-SMs) and in particular to the case when several SCs send MT-SMs to the same mobile station subscriber. When several SCs send MT-SMs to the same subscriber, the first SC that establishes a short message dialog is allowed to be fully completed. While the short message dialog for this SC is established, any other SC attempting to send MT-SMs are detected and stored in a waiting list. After the short message dialog is completed, the same radio connection in maintained and each of the short messages corresponding to the SC addresses stored in the waiting list are sent by a first in-first to send principle.      More generally, the system and method controls messages sent by SMS during a busy condition which enable a better utilization of the network and the network entity resources.

Filed: 1997-08-14
Abstract: A system and method for identifying and processing individual patients among a set of patients includes storing position data representative of patient-unique arrangements of targets that are affixed to the patients for aligning a therapeutic radiation beam. Subsequent to the recording of the position data, a particular patient and/or the medical information of the particular patient can be identified by reimaging the targets or substitute targets on the particular patient to detect a correlation between the image data and the stored position data. The correlation may be used to register a patient, track the location of the patient within a multi-station facility, or facilitate treatment setup, such as beam-to-patient alignment, radiation configuration, and beam control.

Patent CA-2218569-A1 (CA)
Title: Resource sharing for book-ahead and instantaneous-request calls
Inventor: GREENBERG ALBERT GORDON
IPC: H04L12/56
Filed: 1997-10-16
Abstract: Because it is difficult to provide adequate quality of service to large-bandwidth calls in integrated-services networks, service providers may allow some customers to book ahead their calls.  The present invention provides a scheme  resource  sharing among book-ahead calls  (that announce their call initiation and holding times upon arrival) and non-book-ahead calls (that do not announce their holding times and enter service immediately,  if admitted).   The basis for this sharing is an admission control algorithm in which admission is allowed if an approximate interrupt probability (computed in real time) is below a threshold.  Simulation experiments show that the proposed admission control methodology is superior to alternative schemes that do not allow interruption, such as a strict partitioning of resources.

Title: Optical trap for detection and quantitation of subzeptomolar quantities of analytes
Inventor: KISHORE RANI BAKHRU
IPC: G01N33/566
Filed: 1996-06-07
Abstract: Tightly focused beams of laser light are used as "optical tweezers" to trap and manipulate polarizable objects such as microspheres of glass or latex with diameters on the order of 4.5 µm. When analytes are allowed to adhere to the microspheres, small quantities of these analytes can be manipulated, thus allowing their detection and quantitation even when amounts and concentrations of the analytes are extremely small. Illustrative examples include measuring the strength needed to break antibody-antigen bonds and the detection of DNA  sequences.

Title: Motion detector with side-pivoting light fixture
Inventor: LEE WADE
IPC: F21V23/04
Filed: 1996-08-08
Abstract: A light fixture controlled by a passive infrared motion detector including a base (10), one or more lamp holders (11) attached to the base, and a detector housing (12) also attached to the base and containing the motion detector. The lamp holders each comprise a socket housing (13) for receiving a floodlight bulb (16) or the like and a shade or reflector (17) at the front of the socket housing (13). The lamp holder assembly is connected to the base (10) by a support arm (21) that is pivotably connected to a side wall of the socket housing (13) offset from the end of the socket housing instead of being connected at the end of the socket housing as is conventional. The pivoting side mounting (22) of the lamp holder permits the lamp holder to pivot with a moment arm (24) that is significantly shorter than the overall length of the lamp holder. The shortened moment arm permits the motion detector housing to be mounted closer to the supporting base while leaving sufficient space for the lamp holders to swing through a wide range of movement without the risk of inducing false activations through interference with the movable motion detector housing (12).
