Abstract: A structure of any of a pair of stainless steel composite chopsticks, the chopstick is comprised of a main body and a stainless steel metallic sleeve portion combined with each other in injection molding. The chopstick is characterized by: the sleeve portion has a flared opening in connecting with the main body, the opening is located nearly at the middle of the length of the chopstick to be formed, and is provided on the periphery thereof with at least one hole for combination during fabricating the main body by injection molding. The main body can be given a particular pattern; thereby, the two kinds of materials for the chopstick can be firmly combined with each other against dropping, and hardness of the chopstick can be increased. The main body can be more beautiful by providing the particular pattern and the sleeve portion.

Abstract: Disclosed is focus control method for Delta-Sigma based image formation devices in which a steering term and a focusing term of a delay formula are respectively quantized, and corresponding two channels at both sides of the probe are synchronized by a delay produced during dynamic focusing. During synchronizing the two channels, two numeral values with equal absolute value but with opposite signs are respectively inserted so as to eliminate extra noise the signals are after summing up, and controlling common delay of the two channels is performed by same one controller. After summing up the inserted two values, the dynamic aperture control of the Delta-Sigma based image formation device can be effectively realized and noise during dynamic focusing also is eliminated thereby achieving an ideal single bit output.

Abstract: A system architecture for facilitating wireless communications includes a processor configured to implement interference avoidance processing and interference control processing for one or more groups of devices of a packet-communications system. The interference avoidance processing provides different addresses and a common clock for each of the groups of devices to minimize a frequency collision probability for the devices. The interference control processing detects when a same frequency element is selected for more than one of the devices for a same time slot and implements rescue processing to save data packets that are going to collide from being lost. In a preferred embodiment, the interference avoidance processing includes choosing particular address bits to provide the different addresses.

Abstract: A combined type stainless steel chopstick formed by at least two materials is disclosed. The chopstick is formed by tightly combining a holding body with a stainless steel cover, and a front section of the stainless steel cover has a textured surface. The cleaning work is easy, and the cambered edge causes no residue left on the chopstick. Moreover, the defect of generating bacterial on the chopstick as that in the prior art chopstick is improved. The chopstick is made of at least two materials so that the holding sense is preferred, further, since the clamping portion has a textured surface, the clamping effect is good.

Abstract: Tableware grip structure with comfortable touch feeling including a grip and a fitting body. A front end of the grip is disposed with a fitting section formed with a fitting slot at front end for fitting with a tableware. The grip is formed with multiple arch bulge sections and multiple recessed sections which are interlaced with each other. Each recessed section is formed with at least one through hole. The fitting body is correspondingly fixedly fitted on the recessed sections of the grip. The outer circumferences of the bulge sections and the fitting body together form a waved face for a user's hand to more snugly hold and more conveniently turn the grip and achieve a more comfortable touching feeling.

Abstract: A water drainable threshold construction includes a first extrusion which has a longitudinal outside portion adapted to be placed outwardly of a bottom edge of a door, and a longitudinal inside portion lower than the outside portion. The inside portion has a space adapted for receiving water that flows from the outside portion. A tube extends from the inside portion to an outside portion for draining water from the space to the outside of the outside portion. A second extrusion is longitudinally mounted on the inside portion to cover the space, and has holes for passage of water into the space.
