Abstract: A projection device includes a housing, a projection module, a support member, and a cover. The housing includes a rear wall and a plurality of side walls extending from the rear wall. A cavity and an accommodating groove are defined in the rear wall. A projection module is pivotably mounted in the cavity and rotatable along a first direction. A support member is pivotably mounted in the accommodating groove and rotatable along a second direction that is reverse to the first direction. The cover is attached to the housing for covering an opening surrounded by the plurality of side walls.

Abstract: A cover includes a placing plate, a supporting plate, and a connecting portion. The placing plate is placed on a desktop. The supporting plate supports an electronic device. The connecting portion is connected between the placing plate and the supporting plate. A plurality of positioning pieces is placed on the connecting portion, a first joint between the connecting portion and the placing plate, and a second joint between the connecting portion and the supporting plate. The plurality of positioning pieces is elastically bent in different angles to position the supporting plate in different inclined positions.

Abstract: An assembly includes a tablet computer and a docking station. The tablet computer includes a first connection hole defined on a bottom edge of the tablet computer. The docking station includes a base and a supporting seat. The base includes a base body and a control module. The supporting seat is pivotally mounted on the base body. The supporting seat includes a supporting portion. A connecting post is formed on the supporting portion. The connecting post is electrically connected to the control module. The supporting portion supports the tablet computer thereon with the connecting post inserted in the first connecting hole. The connecting post is electrically connected to the tablet computer via the first connecting hole, and the control module is configured to control the tablet computer.

Abstract: A data storage device assembly includes a first data storage device, a second data storage device, a bracket, and a circuit board. The bracket includes a first clamping portion, a second clamping portion, and a connecting portion. The first clamping portion and the second clamping portion extend from the connecting portion and are located on two opposite sides of the connecting portion. The circuit board is secured to the bracket. The first data storage device is secured to the first clamping portion and electronically connected to the circuit board. The second data storage device is secured to the second clamping portion and electronically connected to the circuit board.

Abstract: A voltage-to-digital converting device includes a first voltage-to-time converter outputting a first delay clock having a first time delay relative to a reference clock in response to an input voltage, and a second voltage-to-time converter outputting a second delay clock having a second time delay relative to the reference clock in response to a feedback voltage. The first and second time delays correspond respectively to the input and feedback voltages. A time-to-digital converting circuit receives the first and second delay clocks from the first and second voltage-to-time converters, compares phases of the first and second delay clocks, generates the feedback voltage based on result of phase comparison made thereby, and outputs a digital signal upon detecting that the phases of the first and second delay clocks are in-phase.
