Theft increases the average product cost to consumers. A mentoring system is presented that can help to reduce or prevent the inventory from lost or theft. Theft is a serious concern in the consumer market place. Industry loses billions per year on theft of merchandise. According to a Reuters report, last year, thefts by employees of U.S. retail merchandise accounted for $15.9 billion, or 44 percent of theft losses at stores, more than shoplifting and vendor fraud combined. Thus, the total thief by the customers and store employees during the year 2008 amounted to $36 billion. Several embodiments of ways to control or reduce the thefts in the market place are presented.

A control method for controlling terminal state switching includes a terminal obtaining first data of the terminal and second data from a wearable device that is bound to the terminal when receiving an unlocking instruction in a lock screen state. If the first data and the second data meet a preset condition, the terminal performs the operation of unlocking.

A smart ring includes a battery, memory, processing circuitry, a plurality of sensors, a plurality of antennas, and a battery, each coupled to one another and all enclosed in a casing, wherein the processing circuitry is configured to conserve the battery by any of sending data to the cloud service when an application is open on the user device, sending data to the cloud service when a threshold is crossed, waking up processing or communicating when there is a change in motion detected by the accelerometer.

Disclosed is an electronic device including a touch sensor configured to sense at least one touch on at least two different lateral sides of the electronic device, and a controller configured to determine a state of the electronic device when the electronic device has been gripped, determine a grip pattern based on the sensed at least one touch on the at least two different lateral sides of the electronic device, and perform a function based on the determined grip pattern and state of the electronic device.

A sensor apparatus includes a photosensitive sensor, a cover, and a moving mechanism. The photosensitive sensor includes a first lens and a second lens which focus on a photosensitive element. The cover includes a first slit arranged on an optical axis of the first lens and a second slit arranged on an optical axis of the second lens. The moving mechanism is configured to move the photosensitive sensor and the cover relative to each other so that the second slit is arranged on the optical axis of the first lens.
