Abstract: Various embodiments of the present disclosure are directed towards a method for forming an integrated chip, the method includes forming a through substrate via (TSV) in a first substrate. The TSV continuously extends from a first surface of the first substrate to a second surface of the first substrate. A conductive contact is formed on the second surface of the first substrate. The conductive contact comprises a first conductive layer disposed on the TSV. An upper conductive layer is formed between the conductive contact and the TSV. The upper conductive layer comprises a silicide of a conductive material of the first conductive layer.

Abstract: A multilayer PCB structure includes a core layer, a first layer on a first surface of the core layer, a second layer on a second surface of the core layer, and a thermally conductive material in the core layer. The first surface and the second surface of the core layer are opposite to each other, and a window is formed on the second layer by removing part of the second layer. The window of the second layer exposes part of the core layer below the thermally conductive material.

Abstract: A breathable and elastic spacer fabric composite includes a layered fabric and an elastic layer bonded to the layered fabric. The layered fabric is a so-called spacer fabric. The elastic layer has a plurality of substantially uniformly distributed through holes. The elasticity and through holes of the elastic layer render the entire fabric composite elastic while maintaining the breathability of the layered fabric such that the fabric composite is applicable not only to common clothes, but also to products requiring high fabric elasticity, e.g., sporting and medical braces. A method for making the breathable and elastic spacer fabric composite is also provided. The method prevents the adhesive used to bond the elastic layer to the layered fabric from seeping into and clogging the tiny pores of the layered fabric and ensures a high bonding strength between the elastic layer and the layered fabric.

Abstract: A sit-up exerciser has a base, a seat and a footrest assembly mounted on the base, and a linkage assembly mounted between base and the seat. The linkage assembly has a handle arm, a back arm and a linking rod connected to each other. At least one rear resilient element is connected between the seat and the back arm and at least one front resilient element is connected between the footrest assembly and the handle arm. The resilient elements assist in performing sit-ups and the back arm supports a neck and vertebral column to prevent injury and damage.

Abstract: An exercise machine has a stand, a linking assembly, an elastic member, a seat, two handles, two pedals and two wheels. The linking assembly is mounted pivotally on the stand. The elastic member is connected to the stand and the linking assembly. The seat is mounted on the stand. The handles, the pedals and the wheels are attached to the linking assembly. The handles are operated against the elastic members and the linking assembly moves to drive an exerciser's legs to stretch out. Therefore, the exercise machine provides the exerciser to train the muscles of the arms and the legs synchronously.

Abstract: An exercising device has two rails, two feet, two sliding footrests, an articulated assembly, at least one resilient member and two handles. The rails are parallel. The feet are mounted on the rails. The sliding footrests are mounted slidably on the rails. The articulated assembly is mounted on the rails and is connected pivotally to the sliding footrests. The handles are mounted detachably on the articulated assembly. The exercising device allows conditioning of a neck, arms, thighs, abdomen and back, especially vastus lateralis and vastus medialis muscles of the thighs.

Abstract: The rowing massage machine has a base frame, a footrest, a rowing mechanism and a massage device. The base frame has a base. The footrest is mounted on a front end of the base. The rowing mechanism is mounted on the base and has a chair and at least one rowing resilient element. The chair has a seat and a backrest having longitudinal slits. The rowing resilient element is mounted between the footrest and the rowing mechanism. The massage device has four body massaging wheels and at least one massaging resilient element. The massaging rolling wheels are rotatably mounted on rods connected to the base and are respectively mounted through the slits of the chair. The massaging resilient element is mounted between the rowing mechanism and the massage device. When an operator sits on the chair to exercise, he/her receives a foot, back and upper leg massage.

Abstract: A long-acting flexible thermal compress includes an inner compound layer, an outer compound layer, and a thermal filling. The inner compound layer comprises a film layer laminated with a contact layer. The outer compound layer comprises a film layer laminated with a separation layer. The thermal filling is sealed in a space defined by both inner and outer compound layers welded at the peripherals of their respective film layers. The separation layer helps achieve long-acting thermal compress. The contact layer is made of a material with better touch and proper heat transfer properties to prevent burn or frostbite.
