Method for simulating network hold

A first wireless device is operable to perform role management of short-range wireless connections with other wireless devices over short-range wireless links that utilize a short-range wireless protocol, such as the Bluetooth protocol. According to one embodiment, the first wireless device accepts a request from a second wireless device to establish a connection over a short-range wireless link such that the first wireless device temporarily performs a slave role with respect to the connection. Responsive to establishing the connection, the first wireless device initiates a disconnect of the connection and then communicates a new request to the second wireless device to establish a new connection. Upon receiving an acceptance of the new request from the second wireless device, the first wireless device establishes the new connection over the short-range wireless link such that the first device performs a master role with respect to the new connection.

Method and apparatus for performing role management of short-range wireless connections

A charging circuit is provided for coupling a power source to a plurality of loads. The circuit includes a controller that continually senses the output voltage of the power source. The controller may also decouple the power source from the loads to measure the open circuit voltage of the power source. Once the open circuit voltage is known, the controller establishes a threshold voltage that is slightly below the open circuit voltage of the power supply. The controller then begins delivering current to one of the loads by way of a current regulator. Whenever the power source voltage is below the threshold voltage, the controller reduces the current flowing through the current regulator. When the power source voltage is above the threshold voltage, the controller increases the current flowing through the current regulator. In so doing, the charging circuit simultaneously charges both loads, thereby reducing overall charge time.

Method and apparatus for current delegation to a plurality of loads

This invention includes a method for sensing the parasitic impedance in a battery charging system and compensating for these parasitic impedances. In one embodiment, the voltage of the system is measured with no charging current applied. Next, a charging current is applied and a second voltage is measured. The parasitic impedance is then extrapolated and multiplied by a predetermined rapid charging current. The product is added to a predetermined cell termination voltage. The charging means remains in a rapid charge current mode until a voltage equal to the sum of the impedance-current product and the predetermined voltage is reached, wherein the current is reduced to a maintenance charging level.
