  • Patent number: 12342291
    Abstract: A network of access points may be provided. Access points operating in a low power indoor (LPI) mode and access points operating in a standard power (SP or SPI) mode are identified. The access points operating in an SP or SPI mode are sorted by available frequencies and maximum power budget. For each access point in the network, a composite radio frequency (RF) density score is determined, wherein higher density scores correspond to a denser population of access points in the network. If the composite RF density score is above a determined level, the access point that supports frequencies below a threshold level and that have an effective isotropic radiated power (EiRP) above a determined level are determined as a seed candidate. At least one of the seed candidates is determined as a seed access point.

  • Patent number: 12316804
    Abstract: A method and a communication device for changing the shape of a flexible communication device is suggested. The suggested method is initiated by recognizing a request for actuating a haptic effect on the communication device. At least one property associated with the requested haptic effect, and at least one property of the communication device, where the latter is being caused by the shape of the communication device, are determined. Based on the mentioned properties, a determination is made on whether conditions, specifying requirements for reproducing the haptic effect on the communication device, are met or not. In case the mentioned conditions are not met, a modification of the shape of the device is determined, such that after such a modification the conditions are met with respect to the mentioned properties.

  • Patent number: 12316371
    Abstract: An electronic device may include a transceiver, an antenna, and a front end module (FEM) coupled between the transceiver and antenna. Components on the FEM may operate on radio-frequency signals. The FEM may include a digital controller with a leakage management engine. The leakage management engine may monitor power supply voltages received by the FEM. In response to detection of a trigger condition, the leakage management engine may power off a set of the components while at least some of the FEM remains powered on. The trigger condition may be a change in the power supply voltages or a host command received from a host processor. Using the leakage management engine to power off the set of front end components may serve to minimize leakage current on the FEM, thereby maximizing battery life and shelf life for the device, without the use of bulky and expensive external load switches.
