Exemplary embodiments described in this disclosure are generally directed to using a vehicle to provide building security. In one exemplary embodiment, a computer that is provided in a vehicle is communicatively coupled to various sensors included in an anti-theft security system of the vehicle. The computer automatically activates a building security procedure upon determining that the vehicle has entered, or is located inside, a geofence of a residence. The sensors are configured to detect a security event that may take place near the residence. For example, a motion sensor may be used to detect a burglar approaching the residence or a sound detector may be used to detect shattering of a glass window of the residence. Upon detecting such a security event, the anti-theft security system of the vehicle may transmit a security alert to an individual and/or a monitoring service.

A method of detecting intrusion events including at least two different event types which have different characteristics of frequency and time comprises providing a sensor responsive changes in a medium generated by a potential intrusion event with the sensor generating an output signal indicative of the changes in the medium, analyzing the signal to determine changes in amplitude so as to detect the change in amplitude of the detection signal as a function of time, and performing at least one of: (i) in the frequency domain, carrying out a frequency analysis of the signal from the sensor and dividing the frequency analysis into separate sections which are selected so as to correspond to the characteristic frequencies for each event type, or (ii) the algorithm requiring the presence or absence of a time domain step function.

A multifunctional smart holder and a control method thereof. The multifunctional smart holder is placed on a vehicle device and used for holding a portable device. The multifunctional smart holder comprises: a near-field sensing circuit, a wireless charging circuit and a control circuit. The near-field sensing circuit performs a near-field sensing program to sense a near-field distance between an object to be tested and the multifunctional smart holder to generate a near-field sensing signal. The wireless charging circuit performs a wireless charging program. The control circuit determines whether the portable device is to be placed in the multifunctional smart holder, or taken out from the multifunctional smart holder according to the near-field sensing signal, so that the multifunctional smart holder clamps or releases the portable device, and performs a program for mitigating noise interference to reduce noise generated by the wireless charging circuit when performing the wireless charging program.

It is provided a method for determining when a break-in attempt is in process. The method is performed in a break-in determiner and comprises the steps of: determining that a first vibration condition is tme when a vibration parameter associated with a barrier is greater than a first threshold, wherein the first vibration parameter is obtained from measurements from an accelerometer; determining whether an acceptable activity condition is tme or not, such that the acceptable activity condition is true only when there is an auxiliary signal indicating acceptable activity comprising determining that the acceptable activity condition is tme only when a time difference between determining that the first vibration condition is true and receiving the auxiliary signal is less than a threshold duration; and determining that a break-in attempt is in process when the first vibration condition is tme and the acceptable activity condition is false.

Examples of systems and methods for locating movable objects such as carts (e.g., shopping carts) are disclosed. Such systems and methods can use dead reckoning techniques to estimate the current position of the movable object. Various techniques for improving accuracy of position estimates are disclosed, including compensation for various error sources involving the use of magnetometer and accelerometer, and using vibration analysis to derive wheel rotation rates. Various techniques utilize characteristics of the operating environment in conjunction with or in lieu of dead reckoning techniques, including characteristic of environment such as ground texture, availability of signals from radio frequency (RF) transmitters including precision fix sources. Navigation techniques can include navigation history and backtracking, motion direction detection for dual swivel casters, use of gyroscopes, determining cart weight, multi-level navigation, multi-level magnetic measurements, use of lighting signatures, use of multiple navigation systems, or hard/soft iron compensation for different cart configurations.
