Abstract: Bands for wearable devices include multiple band retainers used to maintain engagement between an assembly (e.g., a pair) of bands. Some band retainers may be permanently affixed with the band at a certain location of the band, while other band retainers can be removable. The removable band retainers can be moved to different locations of the band, thus allowing the band retainer to retain another band at different locations. As a result, the assembly of bands can be used with different users, and in particular, users with different wrist sizes. Moreover, using multiple band retainers can provide an engagement force between the bands to withstand higher-impact events, such as swimming and diving. Additionally, bands and band retainers may include one or more liquid-resistant and corrosion-resistant materials.

Abstract: In a track control method for marking a label side of an optical disc, a data side of the optical disc is first oriented to an optical head. A light beam is then emitted and a sled carrying the optical head moves. A series of moving distances of the sled are calculated according to the light beam reflected by the optical disc, which are then recorded in a memory. The optical disc is then flipped to have the label side face the optical head, and the shift of the optical head is controlled to mark on tracks of the label side according to the series of moving distances recorded in the memory.

Abstract: The present invention discloses a system for speed error compensation. A predetermined speed signal subtracts a feedback speed signal to generate a speed error signal, and a microprocessor receives the speed error signal and outputs a calculated result. A feedback controller receives the calculated result and generates a first tracking control effort signal. A feedforward controller receives the speed error signal and generates a second tracking control effort signal according to a DC steady state error in the speed error signal. An optical head module moves at an actual speed determined by the total of the first tracking control effort signal and the second tracking control effort signal. A gain controller generates the feedback speed signal according to an actual speed signal detecting from the actual speed.

Abstract: The present invention discloses a method of detecting orientation of an optical disk drive. Firstly, a first moving distance is measured by using a first force driven on a movable optical pick up head of the optical disk drive for a preset period. Next, a second moving distance is measured by using a second force driven on the movable optical pick up head for the preset period, wherein the second force and the first force have opposite direction but the same amplitude. Next, it is determined that the optical disk drive is horizontal orientation when the difference between the first and second moving distances falls within a pre-determined value. Additionally, a first moving time is measured by using a first force driven on a movable optical pick up head for a pre-determined distance.
