Abstract:
A portable wireless communications device such as a telephone handset having a vertically corrected antenna module pivotally secured to the handset for rotation about a first pivot axis. The antenna module can be rotated into a predetermined orientation, independent of handset orientation. An antenna mounted on the module is oriented vertically when the module is in the predetermined orientation. When the antenna module is rotated for use, a mechanism incorporated in the module support structure automatically rotates the antenna module about a second pivot axis which is substantially perpendicular to the first. This second rotation places the antenna at an angle that compensates for tilting of the handset during use about an axis parallel to the second axis, or along the first. That is, the antenna is shifted by a preselected angle in vertical orientation, typically around 10-15 degrees, in a direction perpendicular to the first direction of rotation to compensate for positioning a speaker and microphone for use.
Abstract:
Un dispositivo de comunicaciones inalámbrico portátil tal como un microteléfono (10, 110) que tiene un modulo de antena verticalmente corregido (34, 134) asegurado pivotalmente al microteléfono (10, 110) para su rotacion alrededor de un primer eje de pivote (40, 140). El modulo de antena (34, 134) puede girarse en una orientacion predeterminada, independientemente de la orientacion del microteléfono. Una antena (24, 124) montada sobre el modulo (34, 134) se orienta verticalmente cuando el modulo (34, 134) se encuentra en una orientacion predeterminada. Cuando el modulo antena (34, 134) se gira para usarse, un mecanismo incorporado en la estructura de soporte del modulo (34, 134) gira automáticamente el modulo de antena (34, 134) alrededor de un segundo eje de pivote (190), el cual se encuentra substancialmente perpendicular al primero (40, 140). Esta segunda rotacion coloca la antena (24, 124) en un ángulo que compensa la inclinacion del microteléfono (10, 110) durante el uso alrededor de un eje paralelo al segundo eje (190), o a lo largo del primero (40, 140). Es decir, por utilizarse la antena (24, 124) se desplaza mediante un ángulo preseleccionado en orientacion vertical, típicamente alrededor de 10-15 grados, en una direccion perpendicular a la primera direccion de rotacion para compensar la colocacion de una bocina y un microfono (26, 28).

Exemplary embodiments are directed to energy storage device security. An energy storage device may include at least one energy storage cell and a controller. The controller may be configured to request device identification data from an electronic device coupled to the energy storage device and compare the device identification data to device identification data stored in the energy storage device. The controller may be further configured to enable energy to be conveyed from the at least one energy storage cell to the electronic device if the device identification matches the stored device identification data.
Abstract:
Exemplary charging device includes a processor and charging current for coupling to a battery. In an exemplary embodiment, the processor defines charging profiles for charging the battery at different charge rates. A profile can be selected based on a determinable time event and may be modified based on a charging history. Adjustable charging power is supplied to the battery at a power level, a charging duration, or a combination thereof based on the selected profile. A wireless power transmitter can also define charging profiles and charging histories for receivers that receive power from the transmitter based on an identifier from the receiver. The transmitter can select the charging profile based on a determinable time event and may be modified based on a charging history. The transmitter supplies power through the wireless power link at a power level, a charging duration, or a combination thereof based on the selected profile.
