    摘要: A battery charger (102) includes an input terminal (124) for receiving control signals from radio (104). The control signals are received by a charge controller (112) which provides a charge rate to radio battery pack (106) which is a function of the control signal. Radio (104) includes a controller (126) which can sense the state of the radio battery pack (106), as well as changes in the state of radio (104). Controller (126) can then modify the control signal sent to charger (102) and therefor the battery charge rate proved by charger (102) based on certain changes in the state of battery pack (106) or radio (104).

    摘要: A battery charging system includes a battery pack (106) and charger (102). Battery pack (106) includes a selectable magnetic field generator (202) which is activated by radio controller (206) when radio (104) changes states. A Hall-effect switch (204) located in either charger (102) or battery (106) receives the magnetic field and informs charger monitor circuit (128) that radio (104) has changed states. This allows for charger (102) to modify the amount of current being provided to radio (104) via line (129). In a second embodiment, an infrared source (402) and an infrared detector (404) are used in place of selectable magnetic field generator (202) and Hall-effect switch (204).

    摘要: A battery charging system (200) includes a field-effect transistor (212) as a current discharge protection device in order to prevent current from flowing from battery (222) to charger (202) when charger (202) is not charging or discharging battery (222). The field-effect transistor (212) also protects battery (222) in the case that the battery contacts are inadvertently shorted. When charger (202) is charging battery (222), field-effect transistor (212) is turned on, providing for reduced voltage drop across the device due to its low on resistance, and also allows for charger (202) to charge and discharge (condition) battery (222).

    摘要: A vehicular battery operated charger (202) for charging an electronic device such as a radio (204) includes a controller (218). Controller (218) determines the battery voltage of the vehicles battery (222) and compares it to a threshold level stored in controller (218). Charger (202) will automatically charge radio battery (206) as long as the voltage level of the vehicles battery (222) does not drop below the threshold level stored in controller (218).

    摘要: A battery charging system (10) includes a charging path (50) for charging batteries (14) which have a variety of different charging parameters requiring different optimum charging algorithms (58). The battery charging system (10) comprises a charging algorithm sensing circuit (30). At least one battery cell (14A, 14B) having a positive (23) and a negative terminal (27) and an optimum charging algorithm is to be charged. An impedance (R18) having two terminals and a value related to a predetermined charging algorithm of the cell approximating the optimum charging algorithm is coupled to one of the positive or negative terminals of the battery cell (14B). A capacitor (C72) combines with the impedance (R18) to form a characteristic related to the predetermined charging algorithm. Battery terminals (23 and 27) connected to the cell (14A and 14B) and to one of the terminals of the impedance (R18) form a battery (12) for connecting the cell (14A-B) into the battery charging system (10) with the cell (14A-B) in the charging path (50), and the impedance (R18) and the capacitor (C72) in the charging algorithm sensing circuit.

    摘要: A fire hose (100) includes one or more conductors (107) acting as a feed line that is integrally woven into the fire hose side wall (109) and extending at least partially along a predetermined length of hose. One or more slots (113) expose the conductor (107) for transmitting and receiving radio frequency (RF) energy. The RF energy is transmitted and received bi-directionally along into the conductor (107) along the length of the fire hose. This provides stations positioned along the fire hose to have enhanced two-way radio communication without the disadvantage of signal degradation due to a firefighter's location within a building.
