Abstract: Described are techniques and systems for obfuscating a location of a computing device as determined using data acquired from wireless devices within communication range of the computing device. The computing device may be configured to generate report data that includes synthetic data which is representative of data of a different location than the actual location of the computing device. As a result, when the report data is analyzed, the computing device appears to be present at an apparent location which differs from the actual location.

Abstract: An activation signal is provided in response to a user gripping force incident to a grip switch. Electronic circuitry transitions from an inactive state to an active state in response to the activation signal. The activation signal may also include encoded information regarding user identity, gripping force magnitude, user input gesturing, and the like. The electronic circuitry may use the information encoded in the signal to select or perform particular functions or operations. Power consumption of a stylus, user device, or other apparatus is reduced, or various functions are improved, accordingly.

Abstract: A first device wirelessly transmits beacon frames having distinct identifying contents within each. The first device issues a request to a second device to report what beacon frame contents the second device may have received. The second device sends a response to the first device. The first device analyzes the response in view of the beacon frame contents actually sent, the respective radio-frequency broadcast power of the beacon frames, and so on. Based on the analysis, the first device may determine proximity or other information regarding the responsive other device.

Abstract: A system and method for sharing content with a group of devices based on proximity. A sharing device transmits an SSID and an audio signal containing a key. The audio signal may be controlled to limit the area in which the audio signal may be received or heard by a receiving device. For example, the audio signal may be controlled to limit receipt to a device at a same table (a few feet away from the first device), in a same room, etc. This allows the sharer to selectively share content with one or more receiving devices without sharing with all devices in proximity to the first device.

Abstract: A user device acquires identifiers and signal strengths corresponding to detectable wireless devices. The user device associates one or more of the identifiers with one or more venues, assigning a confidence value to each association. A score value is also assigned to each association based on the signal strengths and the confidence values. One of the associations is selected based on the score values, and is designated as the most likely venue where the user device is located. Information may be accessed or requested, or one or more operations may be performed, in accordance with the most likely venue.

Abstract: A system including an active stylus and a mobile computing device where an electronic signal emitted by the tip of the stylus that the mobile computing device uses to locate the tip is turned on and off when the stylus is not being used to save power. Whether the stylus is being used is determined based on an orientation of the stylus in comparison to an orientation of an electronic writing surface of the computing device. Difference in barometric air pressure or altitude between the stylus and mobile computing device may also be used to turn the tip signal on and off.

Abstract: A wireless communications system mitigates the threat of a man-in-the-middle attack when sharing network credentials with a new device. A new wireless device signals that it needs credentials if no other devices are signaling that they need credentials. The new device provides a visible or audible indicator when requested to do so by a device with credentials. Either in response to approval by a user or automatically in response to the indicator, the device with credentials shares credentials with the new device, which can then establish a connection to the network.

Abstract: A system and method for controlling access to digital content based on proximity and location of a user device. A user device connects to a local network and an audio transmission including a perpetually rolling key is transmitted within a geo-fence in the local area. The user device hears the audio transmission and uses the key to authenticate to a content server over the network. Once authenticated, the user device may then stream content from the content server. In order to terminate access to the content when the user device leaves the geo-fence, the content server may require the key to be retransmitted from the user device at regular intervals to re-authenticate the user device. Other factors such as radio fingerprints from the user device may also be used instead of or in addition to the audio to verify the user device's presence within the geo-fence.

Abstract: A rule-based machine learning system monitors frequency bands to detect transmissions from nearby active transmitters, such as those associated with wireless mobile devices. The system logs unique identifiers (UID) embedded in detected transmissions, recognizes patterns of UID detection over time, and selectively takes action when UIDs are detected and when they are expected but absent.

Abstract: In some cases, a delivery service system may include a handheld electronic device for use with a delivery service (e.g., a grocery delivery service). When operating in a voice input mode, the handheld electronic device may record and store audio data in memory. The stored audio data may be communicated from the handheld electronic device (e.g., via a Wi-Fi connection) to the delivery service for speech processing. When operating in a scanner input mode, the handheld electronic device may record and store item identifier information (e.g., barcode data) in memory. The stored data may be communicated to the delivery service for item identification processing. In some cases, a user interface associated with the delivery service may allow the user to review and confirm an order prior to submission of the order for delivery.

Abstract: In some cases, a handheld electronic device may operate in a voice input mode or a scanner input mode. When operating in the voice input mode, the handheld electronic device may record and store audio data in memory. In some cases, the stored audio data may be communicated from the handheld electronic device (e.g., via a Wi-Fi connection) to one or more remote computing devices (e.g., for speech processing). When operating in the scanner input mode, the handheld electronic device may record and store item identifier information (e.g., as barcode data) in the memory. In some cases, the stored item identifier data may be communicated to the one or more remote computing devices (e.g., for item identification processing).

Abstract: Systems and methods for broadcasting messages carried on one or more beacon signals are disclosed. A message sharing device may identify a message to be broadcast and may transmit the message to a base station to generate a beacon signal or generate the beacon signal itself based at least in part on the message. The beacon signal may include an indication that the beacon signal carries a message. The beacon signal may be broadcast and may be received by one or more message receiving devices. In some cases, the message may include a link to content accessible via one or more networks, such as the Internet.

Abstract: A system and method for confirming a delivery location. A delivery agent equipped with a device, for example, a mobile device, delivers a package to a location. When the package is delivered, the delivery agent triggers a delivery-event on the device, and in response to the delivery-event the device determines an RF fingerprint at the location. The RF fingerprint is stored, and a comparison of the RF fingerprint to previously stored RF fingerprints correlated to particular locations is performed. If the RF fingerprint determined by the first device corresponds to a previously stored RF fingerprint at the correct delivery location, the current delivery location is confirmed as correct.

Abstract: A signal is provided in response to moving contact of a device with an object. Electronic circuitry transitions from an inactive state to an active state in response to the signal and scans a machine-readable code borne by the object. A data signal including or encoding the machine-readable code is provided. The electronic circuitry may transition from the active state back to the inactive state after the data signal has been provided and the present code scanning operation is complete. Power consumption by code scanner devices, user input stylus, or other apparatus is reduced accordingly.

Abstract: This abstract describes an apparatus and method for accurately parking a vehicle within an enclosed space such as a garage. The apparatus uses a compact diode laser and is mounted directly to a ceiling or to a device mounted to the ceiling such as a garage door opener unit. When mounted above the vehicle the bright red laser lines are projected from the laser downward and aligned onto a specific surface for the driver to see such as the top surface of a vehicle dashboard. These lines intersect each other forming an ‘X’ (or ‘cross’). This ‘X’ can be aligned with either an existing dashboard feature or with a ‘target’ which is adhered to the dashboard. When a vehicle enters into a garage the first projected laser line that the driver will see will be the longitudinal line. The longitudinal line enables the driver to adjust the vehicle to the right or left as the vehicle continues into the garage. The second projected laser line appears laterally as the driver pulls forward to a stop.
