Patent CA-2294978-A1 (CA)
Inventor: MEAD COLIN ANDREW
IPC: B63G8/24
Filed: 1998-06-25
Abstract: A depth control device (1) for a subsmersible body comprises a depth monitor (5) and depth controller (6). A variable volume buoyant body operates under the control of the depth controller and comprises three chambers, the first (10) containing air and the secnod and third chambers (7, 8) containing hydraulic fluid. The second and third chambers (7, 8) communicate reversibly with one another by means of a tube (13) and bypass valve (12) in a pump (3), so that a piston (9) at the entrance to the first chamber (10) is displaced in response to movement of fluid between the second and third chambers. Thus, the volume of the buoyant body is varied and hence the buoyancy of the subsmersible body which it controls. To keep the submersible body at a particular depth, a depth trigger value is set in the depth controller (6), so that a reversible change in the volume of the buoyant body is initiated in response to a change in depth sensed by the depth monitor (5) by pumping fluid between the two chambers (7, 8). The depth monitor is generally a pressure sensor and the pump is typically a swash plate pump.

IPC: H04N19/895
Filed: 1998-10-23
Abstract: A method and apparatus for generating blocks of data for an image is described. An image is divided into a localized area 560. For each localized area, pixels are assigned to blocks 565 following a complementary pattern.  The complementary pattern is designed such that most pixels are adjacent to pixels arising from other blocks.

Title: Power control and cell site location technique for cdma systems with hierarchical architecture
Inventor: KRISHNAMOORTHY RAJEEV
IPC: H04B7/005
Filed: 2000-05-19
Abstract: Multiple microcell base stations are located within a macrocell having a single macrocell base station in an hierarchical architecture, and microcell users (µ-users) and macrocell users (M-users) communicate respectively with the µ-base and the M-base using the same frequency band, by appropriately (a) selecting the ratio of the radius r of each µ cell and the average distance d from the M-base (r and d are measured by the "radio distance", which includes the effects of shadowing), and (b) controlling the power level with which uplink (mobile to base) and downlink (base to mobile) messages are communicated. Typically, µ-cell size and location are chosen such that d/r > 10. With respect to uplink communications, the transmit powers of the µ -users in a µ-cell are controlled so that the total received power at the nearest M-base is equivalent to the received power from C M-users, where C  is usually set to unity. As a result, the M-cell basically loses C users worth of capacity, but the total number of users is increased by virtue of the additional µ-users. With respect to downlink communications, as long as the microbase and the macrobase are coordinated systems, the µ-base transmit power is controlled so that at the point of handoff between a µ-base and M-base, the received power at a user from the two bases is equivalent, and the received power at the bases from this user is also equivalent. With this arrangement, the µ-base transmit power is increased as r grows and d decreases in order for this balance to occur. Where the M-base and µ-base have no knowledge of each other and handoffs are not allowed between the two base types, a family of I/Q short codes which are quasi-orthogonal to the existing short (pilot) codes are generated, and these codes are used to distinguish between the M-base and µ-base signals.

Abstract: A method, apparatus, and instructions for establishing a virtual communication channel between applications on different nodes in which one node may be using a communication protocol stack based on one protocol, such as SS7, and another node may be using a communication protocol stack based on another protocol, such as IP. Alternatively, a virtual communication channel may be provided between applications on different nodes in which both nodes use a communication protocol stack based on IP to communicate with each other, but carry SS7 traffic through the communication channel. A gateway is provided in which both SS7 and IP are supported. The gateway allows for logical transport of signaling messages between peer applications on different nodes. Messages for SS7 are placed in data packets for transport to a destination using an IP  connection or link to the destination. Header information also is placed into the data packet to allow for routing of the messages when the packet is received at the destination.

Abstract: Methods of predicting a propensity to develop prostate cancer are presented.  The method consists of measuring the IGF status of an individual. Individuals with high IGF status, as compared with normal reference range values, are at increased risk for developing prostate cancer. More particularly, the IGF status may be determined by measuring IGh-I  levels and/or IGFBP-3 levels. High IGF and low IGFBP levels are indicative of a high IGF status. A method of determining the prognosis of existing prostate cancers or of monitoring disease progression involves determining the IGF/PSA status of an individual.  Individuals with a high IGF/PSA status (both high IGF status and high PSA levels) tend to develop severe prostate cancer and have a poorer overall prognosis.
