Disclosed is a means for receiving an Audio/Video (A/V) signal from an original A/V source and re-formatting and re-transmitting the A/V signal such that it can be displayed on a nearby portable mobile device.

An interface module in a nonplanar form. The interface module includes an electronic device card, such as a SIM or memory card, in a cross-sectional shape that may be, for example, substantially a circle or ellipse, substantially rectangular meeting certain dimensional requirements, or a shape other than a rectangle having at least three sides. Selected embodiments of the card may be a shape other than one having parallel major surfaces. An interface module assembly includes a card and a card reader. Electrical contacts are provided on both the card and the card reader. The contacts on the card may extend around the card to improve opportunity for continuous contact.

In a sectored cell of a cellular communication network, channels are dynamically reassigned from a first sector in the cell to a second sector in the same cell when the loading in the first sector reaches a predetermined threshold. The channels allocated to the cell are further subdivided into subgroups and assigned initially to respective sectors in the cell. During normal operation, the channels in each sector are allocated to users in that sector in the usual manner. When the number of channels allocated in a first sector of the cell reaches a predetermined threshold, the base station controller polls the remaining sectors for unused channels. If an unused channel is found, that channel may be reassigned to the first sector. In one embodiment, the base station controller polls the controller in the nearest co-channel cells before reassigning the channel to prevent co-channel interference.

Communication devices, methods, and computer program products acquire a first time division multiple access (TDMA) time slot on a TDMA carrier frequency to establish a first call and acquire a second TDMA time slot on the TDMA carrier frequency to establish a second call. The first and second time slots are associated with a single TDMA frame, which may allow, for example, a voice call and a data call to be established concurrently. Accordingly, the need for multiple phones to maintain both a voice connection and an Internet connection concurrently on a TDMA network may be obviated. Inasmuch as the two time slots are on the same TDMA carrier frequency, additional frequency synthesizers or tuning of existing frequency synthesizers may not be required.

An electric charging system includes an electrical charger that generates a magnetic force and a device with an electric current generator that receives a portion of the magnetic force in a non-galvanic manner. The electric current generator generates an electric current in response to receiving the portion of the magnetic force and the electric current is received by a battery.

An improved SIM card reader with at least one reader data contact that is connected, typically through a control unit, to a memory, through which reader data contact predetermined software update data may be transmitted for storage in the memory of a mobile telecommunication device. The SIM card reader may be integral to the mobile communication device. In a preferred embodiment, the SIM card reader receives an improved SIM card having a card data contact that cooperatively engages with the reader data contact to electrically couple the reader data contact and the card data contact, thereby to provide a data path through which software update data may be transmitted for storage in the memory of a mobile telecommunication device. The at least one reader data contact may be used to &ldquo;flash&rdquo; the memory of a mobile telecommunication device with software updates, for instance. Additional reader data contacts may be implemented for testing functions, such as, for instance, Received Signal Strength Indication (RSSI), transmission power confirmation, VCO Frequency confirmation, and power level.

A releasable holder for a portable communication device including a base clip adapted to secure to a carrier such as a belt and an article clip adapted to secure to the portable communication device. The base clip includes a channel having a bottom and side walls extending between open opposite ends with overlying flanges on both side walls spaced a selected distance from the channel bottom, and a locking tab extending into an opening in the channel bottom, a biasing member biasing the locking tab into the channel bottom opening. The base clip is securable to the carrier with the channel in a generally horizontal orientation. Two user engageable release tabs adjacent the channel opposite ends are adapted to move the locking tab against the biasing of the biasing member responsive to movement of one release tab toward the other. The article clip includes a locking head adapted to slide in the channel, the locking head having a width greater than the spacing between the channel flanges and no greater than the spacing between the side walls, a height no greater than the selected distance of the channel flanges from the channel bottom, an end disposed adjacent the channel bottom when the locking head is in the channel, the end including a tapered outer portion and an inner recess in one end adapted to receive the release tab when aligned therewith.

An electronic device, such as a radiotelephone, has a magnetic latch that maintains a flip cover in a closed position and an electromagnetic release conveniently positioned for one-handed operation by a user. A first magnetic object is disposed within the housing and a second magnetic object is disposed within the flip cover so as to be magnetically attracted to the first magnetic object when the flip cover is in the closed position. The first and second magnetic objects are configured such that the magnetic attraction force therebetween is greater than the biasing force of the spring member to maintain the flip cover in the closed position. A user-activated magnetic field generator is disposed adjacent to at least one of the first and second magnetic objects and reduces the magnetic attraction force between the first and second magnetic objects relative to the biasing force of the spring member such that the flip cover is urged to the open position.

A multi-rate charging circuit includes charging electronics adapted to condition power received from a power source according to operational settings for one or more charge parameters. A plurality of user-selectable charge sets each include settings for one or more of the charge parameters and one of the charge sets is designated as the current default charge set. The charging electronics assume the settings of the default charge set upon power-up, thereafter the user may select an alternative charge set if so desired. A trigger monitor, such as a current level sensor, monitors for the occurrence of a trigger event, such as low current flow associated with the removal of a battery pack, and generates a reset signal in response thereto. The reset signal causes the charging electronics to automatically assume the settings represented by the current default charge set for its operational settings. Thus, upon the occurrence of a triggering event, the charging electronics reverts to (or continues, as appropriate) the default charge set settings. Accordingly, the charging circuit automatically charges each battery pack according to the default settings unless the governing charge set is changed by the user after that battery pack is connected to the charging electronics.
