Abstract: A wireless terminal is disclosed that interfaces a radio on a radio card to a wireless terminal with a single two-lead cable that is capable of carrying both: (1) RF signals from the radio card to an antenna on a wireless terminal, and (2) radio status signaling from the radio card to a display on the wireless terminal. The wireless terminal comprises (1) an antenna, (2) a first visual indicator that indicates to a user of the wireless terminal when a radio is transmitting, and (3) a signal lead for carrying an RF signal from the radio to the antenna and for carrying a first baseband signal from the radio to the first visual indicator.

Abstract: A time-division radio is disclosed that can use a lower-power energy source than radios in the prior art. An illustrative embodiment of the present invention comprises a time-division transmitter that has a transmit mode and an idle mode, a primary energy storage device and a secondary energy storage device. The radio uses the secondary energy storage device as a kind of "power cache" in which to store power when it is in abundance and from which to draw power when it is scarce. When the transmitter is in idle mode, the primary energy storage device charges the secondary energy storage device and powers the transmitter. But when the transmitter is briefly in transmit mode, and, therefore, requires more power than the primary energy storage device alone can supply, the secondary energy storage device discharges to supplement the power from the primary energy storage device and satisfy the transmitter's power requirements.

Abstract: A radio card is disclosed that is rigid on one end and relatively flexible on the second end. The radio card's 68-pin connector and radio are mounted on the rigid end of the card, and the antenna, which is advantageously fabricated from a flexible material, is mounted on the relatively flexible end of the card. When the radio card is inserted into a PC Card slot in the wireless terminal, the rigid end (with the 68-pin connector) is inserted first. When the radio card is seated inside the wireless terminal's card slot, the flexible end of the radio card (which comprises the antenna) is flexed so that the plane of the antenna is advantageously parallel to the plane of the slot doors or housing or both of the wireless terminal. When the doors and housing of the wireless terminal adjacent to the antenna is unshielded, the antenna can radiate through the doors and housing and can exhibit favorable radio propagation characteristics.
