摘要:
A location is determined (402) at which a subscriber unit (122, 300) communicating with a first wireless system is positioned. A distance between the location and a second wireless system preferred by the subscriber unit is calculated (404), and, based upon the distance, it is decided (408) whether the subscriber unit will scan for a signal from the second wireless system.
摘要:
A wireless messaging unit (122) determines (704) that a first channel (402), which utilizes a first plurality of time slots for transmission, does not have a signal suitable for acquiring synchronization; and, in response, attempts (706) to acquire an initial synchronization with a second channel (404) which periodically transmits a synchronization signal (406) in a second plurality of time slots having a predetermined timing relationship with the first plurality of time slots. After acquiring the initial synchronization, the wireless messaging unit applies (708) the predetermined timing relationship to the initial synchronization to establish a secondary synchronization with the first channel.
摘要:
A table (328) is created (402) for mapping, for ones of a plurality of portable subscriber units (122), a plurality of message types to a corresponding plurality of locations. A message matching one of the plurality of message types is then received (404) by a controller (112), the message intended for a portable subscriber unit. In response, the controller and the portable subscriber unit cooperate to determine (406) the location of the portable subscriber unit. The controller sends (428) the message to the portable subscriber unit when the location matches one of the plurality of locations corresponding to the one of the plurality of message types.
摘要:
A portable subscriber unit (122) provides (402) communications for a user, and monitors (404) a parameter indicative of communication quality during the communications. The portable subscriber unit compares (406) the parameter with a predetermined threshold; and when the communication quality deteriorates (408) such that the parameter reaches the predetermined threshold, the portable subscriber unit determines (412) geographic coordinates corresponding to the location at which the communication difficulty occurred, and adds (414) a communication difficulty report identifying the parameter and the geographic coordinates to a record of communication difficulty reports stored in the portable subscriber unit. When the portable subscriber unit receives (502) a request for the record of communication difficulty reports from a fixed portion (102) of a two-way wireless communication system, the portable subscriber unit communicates (504) the record of communication difficulty reports to the fixed portion.
摘要:
A controller (112) defines (402) a channel pattern specifying a network destination for inbound channel traffic, a subscriber unit address group to which the channel pattern applies, and a predetermined time interval during which the channel pattern is to be active. The controller transmits (406) the channel pattern to a processor (310) which processes received inbound traffic. The processor then manages (412) the inbound traffic in accordance with the channel pattern.
摘要:
Sub-areas (506) within a coverage area of a wireless communication system are defined (702), and transmitters (502, 504) are positioned within the sub-areas. A memory (212, 314), in at least one of a subscriber unit (122) and a controller (112) of the system, is programmed (706) with unique transmitter identifiers (414) and corresponding transmitter locations; and a locator signal (406) is periodically transmitted (708) from the sub-areas during time slots (408) coordinated such that, within a sub-area, no more than one transmitter transmits during each time slot. The locator signal includes one of the unique transmitter identifiers for identifying the transmitter sending the locator signal. The subscriber unit monitors (710) the locator signal to determine propagation delays between the subscriber unit and the transmitters received; and one of the subscriber unit and the controller estimates (712) the location of the subscriber unit from the propagation delays and the transmitter locations corresponding to the unique transmitter identifiers received.
摘要:
A wireless communication system conducts (402) communications between a fixed portion (102) of the wireless communication system and a portable subscriber unit (122) carried by a user; and records (404) a relevant aspect of the communications, thereby producing recorded information. The system determines (405) a current time of day and a current position of the user and makes (406) a comparison of the recorded information with the current time of day and the current position of the user to determine whether an alert is necessary, and generates (412) the alert when the comparison determines the alert is necessary.
摘要:
A method for estimating a duration of at least one surgical procedure based on learning from accumulated historical data is provided. The method comprises gathering historical patient data and hospital personnel performance data. The method also comprises analyzing the historical data and the performance data and learning about surgical procedure durations from the analysis. The method also comprises estimating a duration of a surgical procedure or a combination of surgical procedures based on the analysis and learned procedure duration information.
摘要:
A system for measuring sound levels is provided. The system comprises a processor, a memory, and an application stored in the memory that when executed on the processor receives sound levels recorded by each of a plurality of sound sensors located in a coverage area. The application also samples noise levels from the received sound levels at least one location within the coverage area. The application also derives values based at least on the samples and on estimates of sound attenuation at the at least one location. The application also creates a heat map based at least on the derived values, the heat map representing at least noise levels experienced within the coverage area.
