1. A method comprising:
receiving a peak output power setting command from a base station;
receiving a transmit slot allocation from the base station;
detecting, at a mobile station, an increase in the mobile station’s slot allocation;
responding to said detection by determining whether the received peak output power exceeds a threshold and, if so, modifying an average radio frequency output power of the mobile station over a plurality of slots, by reducing an instantaneous radio frequency output power during each transmit slot or the take up of allocated slots, such that it falls below what would have been an average output power level had the peak output power setting command been complied with in all of the allocated slots;
waiting a predetermined time between determination that said threshold has become exceeded and performing said modifying of the average output power; and
setting a cooling flag at the end of said predetermined time and setting a timer when said threshold is exceeded and the cooling flag is not set,
wherein the timer defines said predetermined time and said modifying of the average output power is performed when the timer times out.
2. A method according to claim 1, comprising running an application program on the mobile station and, when the timer expires, if it is determined that the required power reduction takes the output power below a lower threshold, alerting the application program that the service requiring the increase in the slot allocation cannot be supported.
3. A method according to claim 1, further comprising operating the mobile station in a time division multiple access network.
4. An apparatus comprising a controller configured to control the operation of a mobile station so as to:
receive a peak output power setting command from a base station;
receive a transmit slot allocation from the base station;
detect, at the mobile station, an increase in the mobile station’s slot allocation;
respond to said detection by determining whether the received peak output power exceeds a threshold and, if so, modifying an average radio frequency output power of the mobile station over a plurality of slots, by reducing an instantaneous radio frequency output power during each transmit slot or the take up of allocated slots, such that it falls below what would have been an average output power level had the peak output power setting command been complied with in all of the allocated slots;
wait a predetermined time between determination that said threshold has become exceeded and performing said modifying of the average output power; and
set a cooling flag at the end of said predetermined time and set a timer when said threshold is exceeded and the cooling flag is not set,
wherein the timer defines said predetermined time and said modifying of the average output power is performed when the timer times out.
5. An apparatus according to claim 4, wherein the controller is configured to control the operation of the mobile station so as to:
run an application program on the mobile station and, when the timer expires, if it is determined that the required power reduction takes the output power below a lower threshold, alert the application program that the service requiring the increase in the slot allocation cannot be supported.
6. An apparatus according to claim 4, wherein said mobile station is configured to operate in a time division multiple access network.
7. An apparatus according to claim 4, further comprising a radio frequency output power amplifier.
8. An apparatus according to claim 4, further comprising a mobile station.
9. An apparatus according to claim 8, wherein the mobile station is configured to operate in a time division multiple access network.
10. An apparatus, comprising:
means for receiving a peak output power setting command from a base station;
means for receiving a transmit slot allocation from the base station;
means for detecting, at a mobile station, an increase in the mobile station’s slot allocation;
means for responding to said detection by determining whether the received peak output power exceeds a threshold and, if so, modifying an average radio frequency output power of the mobile station over a plurality of slots, by reducing an instantaneous radio frequency output power during each transmit slot or the take up of allocated slots, such that it falls below what would have been an average output power level had the peak output power setting command been complied with in all of the allocated slots;
means for waiting a predetermined time between determination that said threshold has become exceeded and performing said modifying of the average output power; and
means for setting a cooling flag at the end of said predetermined time and means for setting a timer when said threshold is exceeded and the cooling flag is not set,
wherein the timer defines said predetermined time and said modifying of the average output power is performed when the timer times out.
11. An apparatus according to claim 10, further comprising:
means for running an application program on the mobile station and, when the timer expires, if it is determined that the required power reduction takes the output power below a lower threshold, means for alerting the application program that the service requiring the increase in the slot allocation cannot be supported.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of making a net molded plastic pump housing having a fluid inlet port, a fluid outlet port, and a pressure relief valve port, each in flow communication with a pump cavity, the method comprising the steps of
providing a first mold having has an interior surface topography configured to correspond in negative to exterior topographies of a first portion of the housing and to correspond in negative to topography associated with the fluid inlet port, the fluid outlet port, and the relief valve port of the housing;
providing a second mold having an interior surface topography configured to correspond in negative to exterior topographies of a second portion of the housing;
providing a first core having an exterior shape configured to correspond in negative to interior topographies of a proximate portion of the cavity of the housing; and
providing a second core having an exterior shape configured to correspond in negative to interior topographies of a distal portion of the cavity of the housing;
