US Patent:

20140018096, Jan 16, 2014

Filed:

Jul 16, 2013

Appl. No.:

13/943646

Inventors:

Ramanujam Jagannath - San Jose CA, US

International Classification:

H04W 4/02

US Classification:

4554561

Abstract:

Implementations of the present disclosure involve a system and/or method for indoor mapping. The indoor mapping system may receive wireless signals from wireless devices located in an area and create a wireless signal fingerprint that identifies each signal and the strength of the signal. A user may identify the location that the wireless signal fingerprint was taken on a geo-referenced map. After the wireless signal fingerprints for an area have been mapped, a user may determine a location by taking a wireless signal fingerprint and comparing the wireless signal fingerprint to previously taken wireless signal fingerprints.

International Classification:

G06F 21/32
G06F 21/35
G06F 21/40

Abstract:

A user equipment (UE) is configured to perform a prewarming process, wherein the prewarming process includes concurrently performing a face detection process and an unlock process independent of face detection, determine whether a face detection operation indicates the presence of a face within a field of view of a camera of the UE and disable prewarming for a predetermined time period when the face detection operation is not satisfied.

International Classification:

H04W 28/08
H04L 12/24
G06F 15/18
H04W 28/02

Abstract:

In one embodiment, a computing device determines a plurality of probability-based trajectories a mobile device could traverse through a plurality of access point (AP) cells within a given area depending on an entry point of the mobile device into the given area. A predictive dwell time may also be associated to each AP cell based on how long a mobile device is expected to remain within the respective AP cell. Based on i) current locations of mobile devices, ii) the plurality of probability-based trajectories a mobile device could traverse through the plurality of AP cells, and iii) the predictive dwell time of each AP cell, the computing device can compute a probability of mobile device density surpassing a potential flash crowd threshold within each AP cell at any given future time. In response, the computing device may then perform one or more mitigation actions.

International Classification:

H04L 12/24
H04L 29/06
H04L 12/26

Abstract:

Compact and integrated local key controller apparatuses for remotely managing a network of wireless devices that are connected to a computer network switch. These apparatuses (including devices and systems) and methods of using them may provide secure and fully integrated, stand-alone wireless network controllers that may be accessed remotely without compromising the integrity of the network's firewall.
