摘要:
An electrical interface (125, 215) interconnects an electrical device (110) with a removable battery package (120). The electrical interface (125, 215) includes deflectable cantilever contacts (260) that are preferably located within the battery package (120). Each cantilever contact (260) has a portion (261) anchored to a substrate (250), and a deflectable portion (262) biased against a housing member (240), which deflectable portion (262) is externally accessible via a slot (248) within the housing member (240). Preferably, the cantilever contacts (260) are located within a recessed area (245) on an interior surface (241) of the housing member (240). A corresponding projection (346) extends externally on the housing member (240). The external projection (346) facilitates a plug and socket arrangement for mating the battery (120) to the electrical device (110). The substrate (250) is preferably formed from flexible film material and is structurally supported by a backer (270) attached to the housing member (240).

A push-button assembly for a handheld radio (100) is provided which permits off-axis actuation by a gloved user amongst a crowded radio control environment. The push-button (108) includes first and second guide posts (202, 204) of different length, one guide post also serving as a switch actuator. An alignment guide (206) receives the two guide posts (202, 204). The alignment guide (206) with the first and second guide posts (202, 204) are coupled within a recessed portion (216) of a housing (102) to provide tactile feedback, even during gloved usage. The alignment guide (206) may further provide a light guide (110) which can operate as a third guide post for the radio (100).

A rotary control assembly (200) for a handheld two-way radio (100) provides improved tactile feedback in the form of clicks, even during gloved usage. Assembly (200) includes a housing having a large control knob (108), a rotary switch control (202) having a shaft (204), a shaft extender (206) having a toothed gear element (210), and a ball plunger (302). As the control knob (108) is rotated, the shaft extender (206), toothed gear element (210) and shaft (204), all turn in cooperation. The toothed gear element (210) is loaded by the ball plunger thereby generating a clicking tactile feedback in response to the control knob (108) being rotated. A large control knob (108), suitable for a ruggedized environment, can thus be used in conjunction with a small rotary switch control (202) for improved tactile feedback while maximizing internal space efficiency.

A control assembly (400, 500, 600) for a communication device includes a housing having a light permeable portion (406, 506, 606), along with a rotary control formed of a shaft (408), a knob (508) or belt (608) each having a surface, and a light shining light through the light permeable portion onto the surface. Light sensitive motion detection circuitry (402, 502, 602) detects movement of the surface through the light permeable portion (406, 506, 606). The control can be implemented in high profile, low profile, scroll and slider bar embodiments, all providing a sealed environment to the communication device.

A method of detecting wetness in an accessory jack of a portable communication device (100), such as a two-way radio, is provided. By monitoring an accessory jack detect pin of the radio (104) for a change in resistance (106) that falls within predetermined parameters, a determination can be made (108) as to whether the accessory jack contacts are wet or dry. An alert is provided to a user (110) of the portable communication device that the accessory jack contacts need to be dried.
摘要:
A battery pack (304) and battery charging system (300, 400) provides contactless dynamic battery parameter sensing. A proximity sensor (208) is located in the battery pack (304) to monitor battery parameter measurements taken by battery parameter sensors (206). These battery parameter measurements are transferred to a charger (302) or radio (404) through a wireless link established between an excitation circuit, proximity sensor, and reader. The dynamically measured battery parameter information allows a charger (302) or radio (404) to select or adapt a charging routine based on the battery measurements. The use of a proximity sensor (208) along with battery parameter sensors (206) allow for minimal interface contacts between the radio and charger as well as the radio and battery.

A device assembly (100) has a switch actuator assembly (150) with a sealed interface. The device assembly (100) includes a housing (120) having an opening (126) that provides access to an internal switch (135). A switch actuator (160) selectively actuates the switch (135) through the opening (126). The switch actuator (160) includes a seal (164) that is disposed around the opening (126). An external actuator cover (180) includes a seal support member (185) that positions the seal (164) against a seal mount (128) about the opening (126), when the actuator cover (180) is depressed.
摘要:
A converter console (10) includes a base (36) having a hinge axis (127) at a rearward end and a vertical extension (311) having a base mounting joint (29) at the tip of the extension at a front end. A radio receiving pocket (25) has a handle mounting joint (411) at a first end and a hook (27) at a second end, corresponding to the ends of the base for pivotally mounting the hook around the hinge axis. A collapsible linkage (15) couples the pocket (25) to the base (36) between the base mounting joint (29) and the handle mounting joint (411) for pivotally raising and lowering the pocket and for clamping the pocket down.
