Public displays are used for various purposes. They are used for displaying any kind of information and even for controlling devices such as elevators. In order to provide best possible benefit the public display should be displaying information in a language that the viewer understands and in a manner that the user can read the text on the display. The user preferences may be selected and applied by requesting a user preference indication from a mobile device. If the room includes more than one person the user preference indication is received from a plurality of persons and the decision of user preferences to be used is done then based on the received indications.

Method and apparatus are disclosed for vehicle localization based on wireless local area network nodes. An example disclosed vehicle includes a wireless network controller and a location tracker. In response to losing reception of GPS signals, the location tracker scans for wireless network nodes via the wireless network controller, and when second locations of the wireless network nodes are stored in memory, determines a current location of the vehicle based on a particle filtering technique and received signal strength measurements from the wireless network nodes.

Systems, methods, and non-transitory computer readable media are provided for determining routes within a location. Location information for a location may be obtained. The location information may include terrain information for the location. A set of restricted regions within the location may be determined based on the location information. A set of paths within the location may be determined based on the set of restricted regions. An interface through which information describing the set of paths within the location is accessible may be provided.

A system adjusts an estimated travel time from an origin to a destination to better predict an actual trip duration. The system receives a route from a specified origin and destination. The system receives an estimated trip duration corresponding to the generated route. A machine learned model improves the estimated trip duration by applying data about past trips facilitated by the system and data about traffic-control features associated with a route. For example, the system may use counts of a number of road signs and a number of traffic signals located along the generated route to predict an actual trip duration. In some cases, the system may additionally use data about synchronized traffic lights to predict actual trip duration.

Wireless temperature sensor for sous vide cooking. Wireless sensor penetrates food and is sealed with the food in a bag for sous vide cooking. The wireless sensor communicates with the base sous vide system to read core food temperature to ensure pasteurization temperature and time is reached and to eliminate estimations with fat content, size of food in relation to cooking time by taking a direct read. The temperature sensor contains a battery, powered passible via peltier, or through induction.

A PIM probe that includes a PIM antenna carried on a wand sized for positioning by hand. The PIM antenna is tuned by loop size to receive PIM corresponding to uplink reception channels of a site antenna generated by downlink broadcast frequencies F1 and F2 of the duplex antenna. The PIM antenna vanes may include conductors printed on a PC boards or wire loops. A PIM probe system includes a signal analyzer that displays a representation of PIM received by the PIM antenna. The PIM probe system further includes an RF filter for passing the PIM frequencies of interest and suppressing the test frequencies transmitted by the site antenna, such as a cellular base station antenna. When the site antenna is broadcasting the test frequencies, the technician places the PIM antenna in various locations to detect the presence of PIM in those locations.

Provided are systems, devices and methods for determining a spatial location of a target radio frequency node/nodes of a first type, located in a defined space. The system includes a plurality of radio frequency nodes of a second type also located within the defined space and communicate with the target radio frequency node. A radio frequency node of a third type located within/outside the defined space communicates with the plurality of radio frequency nodes of the second type to determine the spatial location of the target radio frequency node.

Innovative new methods in connection with lighter-than-air (LTA) free floating platforms, of facilitating legal transmitter operation, platform flight termination when appropriate, environmentally acceptable landing, and recovery of these devices are provided. The new systems and methods relate to rise rate control, geo-location from a LTA platform including landed payload and ground-based vehicle locations, and steerable recovery systems.
