Sensing apparatus includes a radiation source, which emits pulses of optical radiation toward multiple points in a target scene. A receiver receives the optical radiation that is reflected from the target scene and outputs signals that are indicative of respective times of flight of the pulses to and from the points in the target scene. Processing and control circuitry selects a first pulse repetition interval (PRI) and a second PRI, greater than the first PRI, from a permitted range of PRIs, drives the radiation source to emit a first sequence of the pulses at the first PRI and a second sequence of the pulses at a second PRI, and processes the signals output in response to both the first and second sequences of the pulses in order to compute respective depth coordinates of the points in the target scene.

A system for delivering a self-guided audio tour to an end user, the system comprising: a central server comprising: a database; a tour instruction file stored in the database, the tour instruction file comprising: a tour type; a tour path comprising a plurality of tour points; an order of the tour points on the tour path; location information identifying the real-world position of each of the tour points on the tour path; and data to be delivered to the end user for each of the tour points on the tour path; and a personal electronic device comprising: a central processing unit; a wireless transceiver in communication with the central processing unit for wirelessly communicating with the central server; a position determination unit in communication with the central processing unit for identifying the real-world position of the personal electronic device; a display in communication with the central processing unit; at least one acoustic output unit in communication with the central processing unit; and a software app running on the central processing unit for: using the position determination unit to identify the real-world position of the personal electronic device; comparing the real-world position of the personal electronic device with the tour path to determine if the personal electronic device is located at one of the plurality of tour points; if the end user is at one of the plurality of tour points, and if the end user reached that tour point following the order of the tour points on the tour path, delivering the data from the tour instruction file for that tour point.

A system and method to automatically modify the functionality of telephones when they are located in particular environments. Located in each such environment is a low power radio transmitter with limited range. When the telephone detects a signal from the low power transmitter, the telephone changes its mode of operation such as by turning off a speaker or a ring signal capability or a normal display capability or a normal key input capability. The environment may be within a vehicle.

A method for visually representing information on a display of a portable electronic device includes receiving location coordinates from at least one other portable electronic device, plotting a visual identifier on a map and displaying the map on the display of the portable electronic device. The position of the visual identifier corresponds to the location coordinates received from the at least one other portable electronic device, which correspond to an actual location of the at least one other portable electronic device. The appearance of the visual identifier is selected to depict the status of the user of the at least one other portable electronic device.

The present disclosure relates to apparatus and method that improves the efficiency of filtering event notifications prior to displaying them in mobile devices. After an event notification relating to a new event occurred in the mobile device is obtained, the notification context associated with the user of the mobile device and/or the mobile device for the event notification is first determined. After that, a relevance degree for the event notification is predicted based on the event notification and the notification context by using a learning algorithm that takes into account past event notifications, associated past notification contexts and user reactions to the past event notifications. It is eventually decided whether to display the event notification to the user of the mobile device based on the predicted relevance degree.

An electronic device includes: a location measurement circuitry; a rechargeable battery; a memory configured to store instructions; and at least one processor. The at least one processor may be configured to execute the instructions to: monitor a usage pattern of the battery while the electronic device operates in a first power management state; acquire, based on determining that the usage pattern of the battery is different from a reference pattern derived from a model, information on a location in which the battery is estimated to be charged and information on a time at which the battery is estimated to be charged using the model; and switch, partially based on the information on the location and the information on the time, the first power management state to a second power management state based on a second maximum driving frequency lower than the first maximum driving frequency.

Systems and methods are disclosed for receiving and transmitting accelerometer data and/or usage data, and analyzing the data to detect movement or usage of the device within a vehicle. A device, such as a mobile device, may detect a device movement event or a device usage event associated with the device. Based on the detection of the device movement event or the device usage event, a time associated with the event may be stored. The device may determine whether another event associated with the device occurs within a threshold amount of time from the time associated with the event. Based on a determination of whether the other event occurs within the threshold amount of time, the device may determine an event session associated with the device. The event session may comprise an instantaneous event or a continuous event. Data indicative of the event session may be transmitted to a server.

The present invention includes a system for providing a mobile-based crowdsourcing platform configured to provide an intuitive and semi-automated means of collecting and managing user-driven data by leveraging text messages. The crowdsourcing platform is configured to leverage a Short Message Service (SMS) communication system for generating and transmitting command text messages to mobile devices of users of the service. The command text messages essentially elicit or otherwise train/educate the user's mobile device to automatically transmit requested data back to the crowdsourcing platform, the requested data including the location or position of the user within a given environment.

An improved system and method for defining an event based upon an object location and a user-defined zone and managing the conveyance of object location event information among computing devices where object location events are defined in terms of a condition based upon a relationship between user-defined zone information and object location information. One or more location information sources are associated with an object to provide the object location information. One or more user-defined zones are defined on a map and one or more object location events are defined. The occurrence of an object location event produces object location event information that is conveyed to users based on user identification codes. Accessibility to object location information, zone information, and object location event information is based upon an object location information access code, a zone information access code, and an object location event information access code, respectively.

Systems and processes that incorporate teachings of the subject disclosure may include, for example, receiving a request for a streaming video application service from a mobile device and, responsive to determining a relationship between a service provider of a wireless access point and a service provider of a cellular network providing the streaming video application service via the cellular services. Responsive to determining that the wireless access point is in a communication range of the mobile device based on a proximity of the wireless access point to the mobile device, a communication session is initiated between the mobile device and the wireless access point. Delivery of the streaming video application service to the mobile device is switched from over the cellular network to over the wireless access point. Other embodiments are disclosed.
