摘要:
Devices and methods for detecting a medical sensor device being attached to a host device are disclosed. The host device includes a reader circuit that can generate an AC pilot signal. When the medical sensor device is being attached to the host device, the AC pilot signal is fed to a non-linear circuit in the sensor device, which responds with a DC signal. The host device compares the magnitude of the response signal with a threshold magnitude. If the magnitude of the response signal is greater than the threshold magnitude, the host device determines that the sensor device is being attached and establishes connection with the sensor device.

According to certain embodiments, a method by a wireless device (210) for reporting a connection status is provide that includes receiving a message from a network node (200). The message may be related to a mobility set associated with the wireless device (210). The wireless device (210) may determine that the wireless device (210) is not connected to a WLAN access point included within a mobility set. A timer may be started, and the wireless device may attempt to establish a connection between the wireless device (210) and at least one WLAN access point within the mobility set before an expiration of the timer. If the connection is established between the wireless device (210) and the at least one WLAN access point within the mobility set before the expiration of the timer, the timer may be stopped. If the connection is not established between the wireless device (210) and the at least one WLAN access point within the mobility set before the expiration of the timer, a report may be sent to a network node (200) to indicate a connection failure.

Method (400) and control unit (500) in a vehicle (100), for avoiding an accident at an unattended crosswalk (110). The method (400) comprises: detecting (401) an approaching crosswalk (110); detecting (402) a VRU (120) in the vicinity of the crosswalk (110); determining (403) that the detected (402) VRU (120) is going to walk across the road; determining (404) distance to the crosswalk (110); estimating (405) velocity of the VRU (120); determining (406) deceleration capacity of the vehicle (100), based on deceleration sensitivity of passengers on the vehicle (100), weight of the vehicle (100), and/or estimated friction between vehicle tyres and the road; and recommending (407) an action to be made by the vehicle (100), based on inputs from steps 401-406.

摘要:
Disclosed herein are techniques and systems for performing wireless-based localization using a zonal framework. An area (i.e., surface or space) may be partitioned into multiple zones, and one or more signal propagation models for one or more wireless access points (APs) may be generated for each zone. The result is a set of zonal signal propagation models that allow for improved model fitness on a per-zone basis. A process includes receiving a location query associated with a wireless communication device, selecting a target zone among multiple available zones of an area, and estimating a location of the wireless communication device based at least in part on one of a signal propagation model associated with the target zone or a fingerprint-based localization. The signal propagation model associated with the target zone may be generated based on training samples observed exclusively within the target zone.

In this invention, we disclose methods directed toward integrating an ad hoc cellular network into a fixed cellular network. The methods disclosed herein automate the creation and integration of these networks. In additional embodiments, we disclose methods for establishing a stand-alone, ad hoc cellular network. In either of these implementations, we integrate or establish an ad hoc cellular network using mobile ad hoc cellular base stations configured to transmit and receive over a variety of frequencies, protocols, and duplexing schemes. The methods flexibly and dynamically choose an access or backhaul configuration and radio characteristics to optimize network performance. Additional embodiments provide for enhancing an existing network's coverage as needed, establishing a local network in the event of a loss of backhaul coverage to the core network, and providing local wireless access service within the ad hoc cellular network.
