摘要:
A micro-projection system applied to a portable electronic device, comprising an optical engine, a control module, and a flat cable. The optical engine projects an image. The control module provides at least one control signal to control the optical engine. The flat cable is detachably connected to the optical engine and the control module respectively. Wherein, the optical engine and the control module are configured in the portable electronic device separately, and the flat cable has a corresponding configuration state for connecting the optical engine to the control module.

An image projection apparatus and an image projection method are provided. The image projection apparatus includes a projection light source, a scanning module, a reflection mirror and an optical detector. The projection light source provides a projection light beam and the scanning module drives the projection light beam to scan along at least an axial direction. The reflection mirror is located on a scan path of the projection light beam. The optical detector detects the projection light beam reflected by the reflection mirror and generates synchronous signals. The image projection apparatus determines a scanning frequency of the projection light beam according to the synchronous signals.

An electronic device with a solid state drive and associated control method are provided. The electronic device includes: a host; a power supply component, for providing electric power to the host and the solid state drive; and the solid state drive including a control unit electrically connected to the host through a bus, a cache memory electrically connected to the control component, and a flash memory electrically connected to the control component. When a remaining power of the power supply component decreases to a threshold value, the host controls the solid state drive to enter a data secure mode and disables the cache memory; and when the remaining power of the power supply component is above the threshold value, the host controls the solid state drive to enter a high performance mode and enables the cache memory.

A block grouping method includes the following steps. Firstly, a link list is established. In the link list, plural blocks are classified into plural groups according to valid data counts of respective blocks. If a host refreshes a stored data of a flash memory of the solid state drive or adds a new data into the flash memory, the valid data count of the block corresponding to the refreshed data or the new data is changed, and the link list is updated according to the changed valid data count of the block. After the garbage collection is started by the solid state drive, the block to be subject to the garbage collection is selected according to the link list, and the garbage collection is performed.

A garbage collection control method for a solid state drive includes the following steps. Firstly, when a garbage collection is started by the solid state drive, a type of a write command from a host is judged. If the write command is not a sequential write command, a first type garbage collection is performed for obtaining a released space smaller than one free block space from a flash memory, and the write command is executed to store a write data into the flash memory. If the write command is the sequential write command, a second type garbage collection is performed for obtaining a released space larger than one free block space from the flash memory, and the write command is executed to store the write data into the flash memory.

A lighting apparatus including a base, a light cover, an optical element, and at least a light emitting element is provided. The light cover having a first opening is disposed on the base and together with the base forms a space. The optical element is fixed on the light cover and substantially covers the first opening of the light cover. The light emitting element is disposed in the space. A light emitted by the light emitting element passes through the optical element and emits from the light cover to form an illumination property of the lighting apparatus, wherein the light cover together with the optical element is movable with respect to the light emitting element. When the light cover and the optical element have different relative positions with respect to the light emitting element, the illumination properties are different.

A disc clamping structure is provided. A fixing base is disposed on a turntable. A plurality of ball seats are disposed around a periphery of the fixing base, and each of the ball seats has an aperture. The balls are received in the ball seats. The elastic members are disposed within the fixing base. The balls are upwardly moved, and the height of the center point of the ball is adjusted according to the thickness of the disc when the disc is clamped on the turntable. A portion of the ball is projected from the aperture of the ball seat before clamping the disc.

The invention provides a multiple-view display system and a method for operating the same, wherein a seat sensor is incorporated into the system so that it is possible to get the information whether a user is present or not. Therefore, only one sensor installed on one side of the multiple-view touchscreen for detecting a proximity of the user to the multiple-view touchscreen is enough to identify the touchevent is given by which user, and no extra device is required.

A solid state storage device receives a device sleep signal and a power signal from a host. The solid state storage device includes a control chip, a sleep control circuit, and a regulator. If the device sleep signal is activated, the control chip temporarily stores a system parameter into a flash memory module and then generates an acknowledge signal. The sleep control circuit receives the power signal, the device sleep signal and the acknowledge signal. If both of the device sleep signal and the acknowledge signal are activated, the sleep control circuit generates a disable state and a wake-up state. Moreover, if the power signal is received by the regulator and the sleep control circuit generates the disable state, the regulator stops providing a supply voltage to the control chip, so that the solid state storage device enters a sleep mode.
