The p-type semiconductor layer includes upper and lower surfaces, and the upper surface is recessed downward to form a plurality of spaced apart recesses for receiving the metal filler elements, respectively.

Abstract: A beverage maker assembly includes an outer cup and an inner cup which is removably received in the outer cup. A filtering unit is received in the inner cup and communicates with a drain hole defined in a bottom of the inner cup so that the beverage can flow to the outer cup. A cover is pivotably connected to a handle of the outer cup and has an operation portion extending radially from a periphery thereof. A pivotal portion extends from the operation portion and has an elongate hole. The pivotal portion is movably engaged with a recess defined in the handle by extending a pin through the handle and the elongate hole to pivotably connect the cover to the handle. The cover is easily opened and closed relative to the outer cup.

Abstract: A two-section chopstick with an improved structure has an upper section, a lower section, and a limiting element. The limiting element is mounted around the sidewall near the bottom end of the upper section. The limiting element has a bent fixing part going through a through hole on the sidewall near the bottom end of the upper section. The fixing part extends into an accommodating space inside the upper section. The fixing part holds a connecting section of the lower section to secure the connection between the upper section and the lower section. Alternatively, a holding section in the lower section can be inserted into the accommodating space, thereby storing the chopstick.

Abstract: A codec device is disposed in a display control device for instantly supplying decompressed image data to manipulating devices in the display control chip. Reference images are stored in compressed format after instantly compressed by the codec device. In addition, MSB portions and LSB portions are separately compressed for gaining higher compression ratio. Predication of the pixel value is also modified in variable length coding. On-chip line buffer is also applied with the instant compression mechanism. Fixed compression ratio is predetermined to actually downsize the chip design for the worst case.

Abstract: An electronic lock includes a mechanism comprising a drive assembly comprising a pinion, a gearwheel including a peripheral flange having openings with a curved edge; a clutch comprising a ring including risers in the openings to engage with the curved edges, a first sleeve in the ring and including a rear projection, a driven member including a groove disengaged from the corresponding projection when the lock is locked, and a first spindle, and a spring put on the first sleeve and urged against the driven member; a second sleeve securely urged against the first sleeve; and a second spindle securely passing the second sleeve into the first sleeve. Turning the pinion will turn the gearwheel, push the risers rearward by sliding along the curved edges, move the ring rearward to fit the projection into the groove, and compress the spring such that turning an outer handle will unlock the lock.

Abstract: An image compression method for compressing groups of pixel data, including the following steps: MSB portions and LSB portions of the pixel data are compressed separately. Further, the LSB portions are grouped according to their associated MSB portions so that similar pixels are compressed together to gain higher a compression ratio. Some LSB portions are truncated to ensure a compression ratio. When performing compression, enhanced variable-length coding is adopted that predicts more accurate dividers by considering weighted combination of adjacent pixels. The quotient of each groups of compression portion is predicted and coded accordingly.

Abstract: A chop stick assembly includes a first section having an open top end and an open lower end into which a second section is retractable inserted. At least one hole is defined through a wall and located close to the open lower end of the first section. A connection member is connected to a top end of the second section and has a protrusion which is removably engaged with the at least one hole of the first section.

Abstract: A method and an apparatus of image and video compression, decoding and display procedure includes: image and video compression by taking the digitized one color per pixel format instead of RGB or YUV per pixel. Manipulation of video decompression and the color processing before being presented to the display device saves the density and I/O bandwidth of the storage device and transmission time. The digitized color components are compressed and stored in the referencing frame buffer and decompressed block by block before motion estimation.

Abstract: A video compression, transmission and decoding procedure includes: reducing the image data by calculating the average of a predetermined number of pixels, calculating the DCT coefficients and dividing DCT coefficients by predetermined matrix of values, and applying fixed length of code to represent the DCT coefficients. Low frequency DCT coefficients of each block of pixels are saved in a temporary storage device, should the data loss or damage happened during transmission, the low frequency DCT coefficients of the corresponding block are decoded to represent the lost data. In audio compression and transmission point, a group of audio samples are separated to be at least two sub-groups of audio samples, should any audio sample is lost or damaged, the interpolated value of the nearest adjacent samples of at least one sub-group is used to represent the lost or damaged audio sample.

Abstract: The differential values of adjacent pixels of a group of pixels are calculated and are re-ordered by referring to the magnitude of pixels of a neighboring line. Another time of calculation of differential values of the re-ordered differential values of adjacent pixels is done and the results go through a procedure of a variable length coding. When complex pattern happened, a market code is asserted to break the calculating the differences of adjacent pixels followed by a new raw pixel data as a reference for a new group of pixel. The variable length coding only keeps the “Quotient” and “Remainder” with the “Divider” implicitly done by prediction.

Abstract: Recovered 8×8 DCT coefficient arrays of all block of a JPEG image is formed by reversely decompressing the JPEG image till the procedure of dequantization. A method of redundancy removal of inter-block same subband AC coefficient and intra-block adjacent subband DCT coefficients is applied by re-ordering the coefficients by magnitude of the neighboring subband or a weighted sum of those. The differential values of both inter-block and intra-block DCT coefficients are calculated and coded by an entropy coder to further reduce the data rate. A short code is assigned to represent the “end of non-zero” of each re-ordered subband AC coefficients.
