Latest Patents

One of his latest patents is titled "Power management for subscriber identity module." This invention introduces a power management technique for a Subscriber Identity Module (SIM) that utilizes a voting process to determine when to power up and power down the SIM. The voting process assesses whether software modules running on a wireless communication device (WCD) require current or imminent access to the SIM. This innovation aims to optimize the use of the SIM without compromising performance. Additionally, a modified security authorization process can be integrated, allowing the WCD to cache a user access code in memory for authenticating the user to the SIM. This feature reduces user inconvenience by eliminating the need to enter the access code each time the SIM is powered up.

Another significant patent is "System selection and acquisition for a wireless device." This invention allows wireless devices with varying capabilities to utilize a single file containing multiple Preferred Roaming Lists (PRLs) for system selection and acquisition. The first PRL in the file is formatted for 1x systems, while the second PRL accommodates both 1x and 1xEV-DO systems. This dual PRL system enables legacy devices to operate efficiently while also supporting newer technologies.
