A switch assembly (100, 200) is adapted to be disposed in a holding portion (50) of a hand-held device (10). The switch assembly (100, 200) includes first (110) and second (120) keys, first (115) and second (125) connecting portions, a switch element (130) and a plunger (140). The first and second keys are exposed on the surface of the holding portion and respectively disposed on the opposite sides thereof. The first and second connecting portions respectively connect the first and second keys and the holding portion. The first and second connecting portions are disposed for allowing the first key having a displacement toward the second key along their connecting direction. The switch element is located inside of the holding portion, and the first key has a first backside (111) toward the second key. The second key has a second backside (121) toward the first key. The plunger is adapted to press and activate the switch element through the displacement.

The disclosure proposes an auto-focus method and an image capturing device including a distance sensor and an image sensor having a lens and a sensing array. The method includes the following steps. First, distance sensor data and phase detection data are respectively obtained from the distance sensor and the sensing array. The lens is controlled to perform a course search within a focusing range by switching between a distance sensor auto-focus mode and a phase detection auto-focus mode based on the distance sensor data and the phase detection data so as to determine a fine-search range. The lens is further controlled to perform a fine search within the fine-search range in a contrast detection auto-focus mode so as to determine an optimal focusing lens position. Next, the lens is controlled to move to the optimal focusing lens position.

The instructions comprise performing a first connection to the communication device by the cellular network; performing a second connection to the communication device by the WLAN; initiating an EAP AKA procedure to the communication device by the WLAN, if the communication device is not configured with a communication of cellular PDUs via the WLAN; and initiating an eNB assisted authentication procedure to the communication device by the cellular network, if the communication device is configured with the communication of the cellular PDUs via the WLAN.


An electronic system includes a portable display device, e.g. head mounted device HMD, and a guiding device, e.g. PDA. The HMD includes a first display unit for displaying images of scenes according to a first field of view, a control unit for generating information of a current viewing area of one of the images to be displayed on the first display unit and a first communication unit for outputting the information of the current viewing area. The PDA includes a second communication unit for receiving the information of the current viewing area from the portable display device and a processing unit for generating guidance information according to the information of the current viewing area. Wherein the second communication unit transmits the guidance information to the first communication unit, and accordingly the control unit performs a guidance task according to the guidance information; i.e. the HMD generates some graphical or textual information overlaid in the current view based on the guidance information received, thereby giving an indication where to move in order e.g. to see a certain location indicated to by the first person on the PDA.


A method for audio-video synchronization in a virtual reality (VR) system is provided. The VR system includes a VR device and a host device. The method includes the steps of: connecting the VR device to a host device via a data transmission interface; transmitting an audio signal and a video signal from the host device to the VR device; estimating time delay information in an audio transmission path and a video transmission path of the VR device; transmitting a feedback signal recording the time delay information from the VR device to the host device; and adjusting timing of the audio signal or the video signal transmitted from the host device to the VR device according to the feedback signal.


A fingerprint enrollment method, an electronic apparatus, a computer-readable storage medium are provided. The method includes following steps. An indication icon is displayed, wherein the indication icon is divided into N regions, N is a positive integer larger than 1, a region of the N regions is initially painted with a first color, and other regions of the N regions are initially painted with a second color. Whether a sensor apparatus is being touched is determined. When determined that the sensor apparatus is being touched, whether to capture a fingerprint image is determined. Each time when the fingerprint image is captured, the region with the first color is painted to a third color, and one of the N regions with the second color is painted to the first color. When number of the captured fingerprint image is up to N, a fingerprint sample is obtained from the captured fingerprint images.


A communication device of handling a wireless local area network (WLAN) measurement configuration comprises instructions of establishing a connection to a base station (BS) of a cellular network; receiving the WLAN measurement configuration on the connection from the BS; performing WLAN measurement on a WLAN according to the WLAN measurement configuration; transmitting a first WLAN measurement result of the WLAN measurement on the connection to the BS according to the WLAN measurement configuration; receiving a cellular-WLAN aggregation (CWA) configuration on the connection from the BS; communicating a plurality of packets with the WLAN according to the CWA configuration; keeping the WLAN measurement configuration, when detecting a connection failure on the WLAN; and releasing the WLAN measurement configuration, when detecting a connection failure on the cellular network.
