Patent CA-2199310-A1 (CA)
Title: Method for determining organization parameters in a wireless communication system
Inventor: CHAWLA KAPIL K
IPC: H04B17/00
Filed: 1997-03-06
Abstract: A level of automated adjustment of system organization parameters in a wireless communication system is provided by determining the parameter settings using a characterization of signal propagation of the system's coverage area. This characterization is based on measurements of path loss-related characteristics by the system's base stations and wireless terminals operating throughout the coverage area. An exemplary path loss-related characteristic is path loss as determined by measuring received signal strength (RSS) at wireless terminals based on signals transmitted at known powers by a plurality of the system's base stations. It is possible for the wireless terminals to take measurements while operating in the coverage area, whether idle or during communication with the system, and for such terminals to be associated with the system's subscribers. A resulting characterization of signal propagation in the coverage area based on the measured path loss-related characteristic can then be used to determine a variety of parameter settings including base station transmission power settings, wireless terminal access parameters, neighbor lists, sets of base stations that can reuse channels and base station transmission power settings when base stations are added to or removed from the system.
Patent CA-2201760-A1 (CA)
Inventor: HAMMER JONATHAN B
IPC: G01S13/933
Filed: 1996-03-15
Abstract: A horizontal miss distance filter system (220) is provided for inhibiting resolution alert messages from an air traffic alert and collision avoidance system (210) to a pilot's display (230). The horizontal miss distance filter employs a parabolic range tracker (10) to derive a range acceleration estimate (11) utilized to discriminate intruder aircraft (110) having non-zero horizontal miss distances. The horizontal miss distance calculated from the range data provided by the parabolic range tracker is compared with a bearing based horizontal miss distance provided by a bearing based tracker (22). The smaller of the two calculated horizontal miss distances defines a projected horizontal miss distance which is compared with a threshold value. Any resolution alert for intruder aircraft whose projected horizontal miss distance is greater than the threshold will be inhibited unless it is determined that the encounter involves a maneuver of one of the aircraft. As many as five maneuver detectors (50, 52, 56, 58 and 64) may be employed to assess whether the encounter involves a maneuver. If any of the maneuver detectors establish the occurrence of a maneuver, then a resolution alert provided from the TCAS system (210) will not be inhibited.

Patent CA-2215369-A1 (CA)
IPC: H01L31/119
Filed: 1997-09-12
Abstract: An insulated gate field effect transistor dosimeter has a source and drain defining a channel region, a floating gate having a first portion extending over the channel region, and a second, larger portion extending away from said region, a control gate having at least a portion thereof overlapping a first part of the floating gate, and a charging gate overlapping a second part of the floating gate. The area of the second part of the floating gate is much smaller than the area of the first part, and the charging gate is separated from the channel region by the control gate. The dosimeter is charged, before irradiation, by connecting the source, drain and control gate to a common ground and applying a potential difference between the charging gate and the common ground. The charge is supplied to the floating gate by a path which does not require a significant electric stress to be created in the region of the gate oxide and the channel. The dosimeter may comprise two such transistors fabricated on a common substrate, conveniently with a common source. The pair of transistors may be charged by maintaining the sources, drains and control gates within the normal maximum operating voltage relative to each other, and applying different potential differences between the two charging gates, respectively, and the substrate. Following irradiation, the absorbed radiation dose is determined by measuring the difference between the threshold voltages of the two transistors. Preferably, the transistors have charges of opposite polarities. This differential arrangement reduces the effects of temperature variations and enhances sensitivity.

Title: Portable device battery technique
Inventor: GREENE MICHAEL ROY
IPC: G01R31/36
Filed: 1997-12-10
Abstract: When a user has a portable telephone near the absolute end of its available battery power, the user can be caused to behave in a manner that more likely results in the preservation of some battery power for subsequent high priority high priority calls by conveying the illusion that the battery will soon be, or is, depleted even though there actually remains sufficient power in the battery to power the portable telephone for an additional period of time. To this end, at a predetermined time, e.g., two minutes, prior to a projected time at which the battery is expected to have power for only a particular additional amount of time, e.g., eight minutes, the user is signaled with an almost-out-of-power warning. This warning indicates that there remains in the battery enough power to operate the portable telephone only until the projected time, notwithstanding that there actually remains in the battery sufficient power to operate the portable telephone for the additional time beyond the projected time. To enhance the illusion of early battery power depletion, the portable telephone powers off at the projected time. Furthermore, any battery power indicator provides the user with an artificially low power reading that indicates that the battery power will be completely depleted at the projected time. At any point after initiation of the almost-out-of-power warning, the user may take an affirmative action to make available the additional power remaining in the battery. At that point, the display is restored to an accurate indication.
