International Classification:

H04M 1/00

US Classification:

455570, 455 306, 4555691

Abstract:

A method () for controlling audio signals to an FM transmitter and a loudspeaker of a hands-free adapter first sends a first audio signal to the loudspeaker () and measures and records a loudspeaker audible artifact such as echo return loss () and/or echo tail length (). Next, the hands-free adapter sends a second audio signal to the FM transmitter and the loudspeaker () and measures and records an FM transmitter and loudspeaker audible artifact such as echo return loss () and/or echo tail length (). If the FM transmitter and loudspeaker audible artifact minus the loudspeaker audible artifact is greater than a threshold (), the hands-free adapter sends a third audio signal to the FM transmitter only (), and if the FM transmitter and loudspeaker audible artifact minus the loudspeaker audible artifact is not greater than the threshold, the hands-free adapter sends the third audio signal to both the FM transmitter and the loudspeaker ().

International Classification:

H04M 100

US Classification:

379428

Abstract:

A modular housing system (100) comprises a first housing unit (102), a second housing unit (104), and a clamp (600). The first housing unit (102) has a first bottom wall (610) and a first side wall (108). The second housing unit (104) has a second bottom wall (612) and a second side wall (116). The first housing unit (102) defines a first channel (702) which borders the first side wall (108) and includes an first opening (703) along the first bottom wall (610). The second housing unit (104) defines a second channel which borders the second side wall (116) and includes a second opening along the second bottom wall (612). The clamp (600) has a longitudinally extending U-shape defining a base (800), a first attachment wall (802), and a second attachment wall (804). For optionally attaching the first and second housing units (102, 104), the first attachment wall (802) insertably attaches within the first channel (702) and the second attachment wall (804) insertably attaches within the second channel.

International Classification:

H04M 100

US Classification:

379446

Abstract:

A telephone apparatus (100) includes a base (102) and a handset (104) configurable in a desktop mode and a wall mount mode. Spring loaded detents (132, 134) in the base (102) engage recesses in the handset (104) in wall mount mode to securely retain the handset (104) in a pocket (101) in the base. The base includes a switchable detent mechanism (170) for retracting the detents (132, 134) in response to an actuator (150) when the base (102) is switched from wall mount mode to desktop mode. Thus, the detents (132, 134) do not interfere with the handset (104) when the handset (104) is placed in or withdrawn from the pocket (101).

International Classification:

US Classification:

228 11

Abstract:

An unwelded battery assembly (32) is fed to a shuttle (36) which moves the unwelded battery assembly (32) to a moveable platform (46) in a raised position. The platform lowers the battery assembly into a nest (44) which rigidly supports the battery assembly. An ultrasonic horn is lowered into contact with the battery assembly and welds the battery cover (16) to the battery housing (14). The welded battery assembly (57) is then raised out of the nest by the moveable platform (46), and is moved to a second stage (48) while another unwelded battery assembly is shuttled to the platform. A central control circuit (49) operates and synchronizes the apparatus.
