A mobile door knocker causes a portal to open for an authenticated user. A physical access control system actuates upon receiving a wireless request triggered by a pattern of indicia in the vicinity of a portal. A hand-held communication device transmits a portal access control signal when it recognizes a pattern of bursts in signal amplitude. A mobile device has a sensor package, communication circuits, and a processor. Upon determining proximity to a controlled portal, the sensor package enables a pattern recognition circuit. Upon receiving a success indicia from the pattern recognition circuit, the communication circuits authenticate with the controlled portal. A sensor package may be enabled by accelerations from tapping the device against a door, wall, or table. A pattern may be related to a number, or a sequence, or combination of slows, pauses, and quicks, or a curvilinear acceleration.

One or more beaconing devices transmit synchronized changing beacons. The changing beacons trigger execution of an application that is installed but closed or not running on a mobile device, that is in wireless beaconing range of a beaconing device, and that has registered the changing beacons with the mobile device operating system (OS) to trigger execution of the application upon receipt of the changing beacons. The changing beacons also keep the executing application running by resetting OS policies for closing the application when it is running with the mobile device in a locked or standby state. The application may perform different procedures and different times with the beaconing device or other devices including authorizing access to a secured resource when the mobile device is far away from the beaconing device, and confirming intent to access the secured resource when the mobile device is close to the beaconing device.

A terminal performs communication with an in-vehicle device to control a vehicle. The terminal includes a controller configured to switch and control an operation mode of the terminal to at least a predetermined first mode or a predetermined second mode, a reception unit configured to receive a first signal including a switching request of the operation mode from the in-vehicle device, a generation unit configured to update a predetermined value with the reception of the first signal and generate a second signal based on the updated predetermined value, and a transmission unit configured to transmit the second signal to the in-vehicle device. When a third signal including a command for instructing switching of the operation mode received by the reception unit is a response to the second signal, the controller switches the operation mode from the first to the second mode or from the second to the first mode.

An intelligent door lock system for a door at a dwelling. The intelligent door lock system includes a door status device is at the dwelling, an engine, an energy source, a memory, and a camera. The door status device is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at the door. The lock device is coupled to the door status device and includes a bolt. The engine, the energy source, and the memory are coupled together. The camera is configured to record in response to door lock status.

A vehicle-mounted apparatus comprising: a main body portion; and an electronic key accommodating portion that accommodates an electronic key of a vehicle and is attachable to and detachable from the main body portion, wherein the electronic key accommodating portion includes a switching unit that switches detection states of a first detection unit and a second detection unit according to an attachment or detachment operation of the electronic key accommodating portion to or from the main body portion, the first detection unit is provided in the main body portion for detecting an accommodation state of the electronic key in the electronic key accommodating portion, and the second detection unit is provided in the main body portion for detecting an attachment or detachment state of the electronic key accommodating portion with respect to the main body portion.

In one embodiment, an apparatus comprises an antenna to receive one or more radio signals, wherein the antenna is associated with a proximity-based access portal. The apparatus further comprises a processor to: detect, based on the one or more radio signals, an access request from a first device, wherein the access request comprises a request to access the proximity-based access portal using an access token associated with an authorized device; determine, based on the one or more radio signals, that the first device is within a particular proximity of the proximity-based access portal; obtain a first motion history associated with movement detected near the proximity-based access portal; obtain a second motion history associated with movement detected by the authorized device; and determine, based on the first motion history and the second motion history, whether the movement detected near the proximity-based access portal matches the movement detected by the authorized device.

Systems, devices, and methods for magnetic fingerprinting for proximity-based systems are described herein. One device includes instructions stored thereon executable by a processor to receive location information associated with a mobile device in a facility, determine that the mobile device is within a particular distance of an area of the facility based on the location information, determine magnetic field information associated with the mobile device, and allow access to the area via a relay associated with the area responsive to a determination that the user is allowed access based on the magnetic field information.

A communication system for facilitating control over a function of a vehicle (102) comprises a base station (104) positioned in the vehicle (102) and a mobile communication unit (122). The base station (104) comprises a first transmitter for transmitting a signal to the mobile communication unit (122) and a first receiver for receiving a signal from the mobile communication unit (122). The base station (104) is further configured to cause the mobile communication unit (122) to operate in accordance with a limited-response duty cycle.

An electronic lock according to an embodiment includes an exterior escutcheon on an unsecure side of the door, an interior escutcheon on a secure side of the door, a printed circuit board assembly (PCBA) positioned within the exterior escutcheon, and a plurality of ultra wideband (UWB) antennas secured to an exterior-facing side of the PCBA, wherein the plurality of UWB antennas comprises a first UWB antenna and a second UWB antenna configured to operate on a first UWB channel, and wherein the second UWB antenna is positioned no greater than one half of a wavelength of the first UWB channel from the first UWB antenna along a first axis.

A sensor system and method for a dynamic change in a touch response time of a door hand touch sensor is provided. The sensor system receives a first communication associated with an actuation setting of the door via the in-vehicle communication bus. The actuation setting includes an option to trigger lock or unlock operations of the door based on a movement of a portable device towards or away from the vehicle. Thereafter, the sensor system controls the touch sensing unit to change a touch response time of the touch sensing unit from a first value to a second value. The change is performed based on the first communication.
