Abstract: A wireless communication device (20) provides a matching state between a radio circuit (28) and an antenna assembly (26) in both its retracted and extended positions, and does so with an elegant design that increases reliability and manufacturability by reducing the number and complexity of components and moving mechanical parts. A matching circuit (30), which is reconfigured according to a switch (32) that is responsive to the antenna's position, provides the matching states.

Abstract: Un montaje de antena contraíble (206, 900) proporciona una impedancia de antena adaptada con un circuito adaptador (712) de un radioteléfono (200) ya sea que el montaje de antena contraíble esté en posicion extendida o en posicion contraída. En una realizacion, las partes (304, 312) de un capacitor (714) sr forman integralmente en una porcion superior del montaje de antena contraíble (206) de manera tal que, cuando está en al posicion contraída, el capacitor (714) contribuye a la impedancia total de la antena. En otra realizacion, un capacitor (1302) se forma íntegramente en la porcion inferior del montaje de antena contraíble (900).

Abstract: A radio communication device a first housing portion (101) and second housing portion (103). The second housing portion is movably supported on the first housing portion to move between an extended position and a collapsed position. The second housing portion projects outwardly from the first housing portion in the open position. An antenna (107) is positioned in the second housing portion, the antenna includes a first component having a first tuning characteristic and a second component having a second tuning characteristic. For example the first component may be a dipole which when the cover (107) of a mobile telephone is extended into free space is tuned to the operating frequency. A second associated component is tuned to the same frequency by the proximity of the rf circuitry in the main housing (101), when the cover (107) is closed. Each antenna is defined in the respective other positions of the cover.

Abstract: A radio communication device (100) includes radio frequency circuitry (415) positioned in the first housing portion (101). A second housing portion (103) is movably supported on the first housing portion to move between an extended open position and a collapsed position, the second housing portion projecting outwardly from the first housing portion in the open position. An antenna assembly (107) is positioned in the second housing portion. The antenna assembly includes an antenna conductor (542) and a flexible ground member (544), the ground member positioned between the antenna conductor and the radio frequency circuitry when the first and second housing portions are in the collapsed position.

Abstract: A method of preparing recombinant ubiquitin cross-reactive protein (UCRP) is disclosed. In one embodiment, the method comprises the step of purifying UCRP from a host cell in the presence of a cobalt or Group IIb metal, wherein the cobalt or Group IIb metal prevents proteolytic inactivation of UCRP occurring by cleavage of the UCRP carboxyl terminal glycine dipeptide. In another embodiment the method comprises purifying UCRP comprising an additional arginine or lysine residue at the carboxy terminal. A preparation of UCRP with an additional arginine residue at the carboxy terminus is also disclosed.

Abstract: A transmitter (135) responds to a first control signal by outputting a transmit signal at a transmit power according to the first control signal. A power-level detector (149) responds to the transmit power by outputting a second control signal representative of a power level of the transmit power. A sensing network (159) is capable of changing from one state to another state in response to a stimulus, for example, the position of a retractable antenna (101) or attachment of a connector (113) or both. The sensing network may modify the second control signal depending upon the state of the sensing circuit. A controller (161) responds to the second control signal, whether modified or not, by determining the first control signal according to the second control signal.
