Exemplary systems and methods enable a user of a mobile device that is communicatively coupled to a remote device to adjust the audio output volume level of an application running on the remote device using audio volume adjustment inputs on the mobile device. The application produces an audio output signal that has an adjustable audio volume output level. The mobile device receives the audio output signal from the remote device. The mobile device detects an audio volume adjustment input. The mobile device redirects the audio volume adjustment to the remote device to control the audio output volume level of the application.

Embodiments disclosed herein enable detection and improvement of the quality of the audio signal using a mobile device by determining the loss in the audio signal and enhancing audio by streaming the remainder portion of audio. Embodiments disclosed herein enable an improvement in the sound quality rendered by rendering devices by emitting an test audio signal from the source device, measuring the test audio signal using microphones, detecting variation in the frequency response, loudness and timing characteristics using impulse responses and correcting for them. Embodiments disclosed herein also compensate for the noise in the acoustic space by determining the reverberation and ambient noise levels and their frequency characteristics and changing the digital filters and volumes of the source signal to compensate for the varying noise levels.

Methods of and systems for resolving multiple location estimate conflicts in a WLAN-positioning system are provided. Disclosed are methods to quantify the probability that a particular location estimate of a mobile device made by a Wi-Fi based positioning system is correct to within an arbitrary accuracy. Implementations use observed access point cluster size, age information for access point location determination, and/or cumulative distribution functions that characterize the conditional probability that one or more access points detected by the mobile device have relocated within a specified time interval to make the probability determinations.

Methods of and systems for estimating the probability of movement of access points in a WLAN-based positioning system are provided. Disclosed are methods to quantify the probability that a particular location estimate of a mobile device made by a Wi-Fi based positioning system is correct to within an arbitrary accuracy. Implementations use observed access point cluster size, age information for access point location determination, and/or the probability that one or more access points detected by the mobile device have relocated based on historic information about the movement of a collection of access points to make the probability determinations.

The mobile device includes a short range transceiver and a network transceiver. The mobile device accesses electronic shop server web sites which contain digital products for sale and hotspot network locations where these digital products may be downloaded to the mobile device via the short range transceiver. The hotspot network locations contain a hotspot device for transmitting the digital products to the mobile devices via the low power radio frequency signal of the short range transceivers when the mobile device has detected the low power radio frequency signal. Using this system, method and computer program, a user of a mobile device may download large amounts of digital data without incurring telephone or cellular phone charges.

A virus scanning system which scans a mobile device/mobile device for files containing viruses even if the files are not executable on the mobile device. Corrective actions such as removing the files can be performed once the viruses are detected. As a result, viruses which are not executable (as being designed for other mobile device types) can also be detected and removed from mobile devices. According to another aspect, a common interface is provided when a virus scanning program requests data from mobile devices, and the computer is provided with different remote application programming interfaces suited to retrieve the specified data from the corresponding mobile devices. As a result, the computer can be extended to integrate scanning of new device types easily. According to one more aspect, a scanning program retrieves only data portions required for continuing the scan operation. According to yet another aspect, the program modules and virus definitions for scanning are received from a server on a network.

A system that tracks information related to security events in a gaming environment includes a plurality of gaming machines, a database storing data regarding security events, and a security event tracking server in communication with the gaming machines and database. Each gaming machine can have an electronic tracking device adapted to detect wirelessly identifying information from portable electronic devices proximate the gaming machine with respect to the occurrence of a security event at or near the gaming machine. The server includes a processor configured to receive information regarding security events and mobile device identifying information, associate the security events with the identifying information, and store the associated security events and identifying information to the database. Mobile device identifying information can be detected passively without any affirmative input by any user of the mobile devices. Patterns of repeated mobile device detections associated with multiple security events can be determined.

A mobile device detects a moveable foreground object in captured images, e.g., a series of video frames without depth information. The object may be one or more of the user's fingers. The object may be detected by warping one of a captured image of a scene that includes the object and a reference image of the scene without the object so they have the same view and comparing the captured image and the reference image after warping. A mask may be used to segment the object from the captured image. Pixels are detected in the extracted image of the object and the pixels are used to detect the point of interest on the foreground object. The object may then be tracked in subsequent images. Augmentations may be rendered and interacted with or temporal gestures may be detected and desired actions performed accordingly.

An apparatus, method and medium detecting landmarks with a mobile device. The apparatus includes a storage unit to store rules of landmarks that correspond to connection relations among items representing a user's living patterns, an analysis unit to statistically analyze the collected log information representing a current living pattern of the user, a landmark probability inferring unit to infer in probability the landmarks according to the analyzed log information based on the stored rules, and a landmark selection unit to select a final landmark by mutually analyzing the stored rules and the inferred landmarks.

A mobile device tracking prevention method and system includes monitoring a mobile device for movement, determining whether an operating state of a wireless module of the mobile device should be adjusted when movement of the mobile device is detected, and controlling the operating state of the wireless module based on the determination. One or more of the actual geographic location of the mobile device, network IDs broadcasted by nearby network access points, and signal strengths of the access points as detected by the mobile device can be monitored to detect movement of the mobile device. Changes to any of these may be indicative of movement of the mobile device, which may serve as the basis for enabling or disabling the wireless module to prevent tracking of the mobile device without sacrificing user productivity.

To improve network coverage or reduce false handover triggering, at least one client terminal is set to operate as a virtual access point (VAP) in a first wireless network by an AP controller. If a mobile device detects that a signal quality estimate of communications via an AP of the first wireless network is below a first value, the mobile device performs a handover procedure to the VAP. While maintaining the call via the VAP, if the mobile device detects that the signal quality estimate is back above the first value, the mobile device performs a handover procedure back to the AP of the first wireless network. On the other hand, if the mobile device detects that the signal quality estimate is below a second value which is less than the first value, the mobile device performs a vertical handover procedure from the VAP to a base station of a second wireless network.
