Abstract: A thin film bulk acoustic resonator (FBAR) includes a first electrode, a first piezoelectric layer having a first c-axis orientation and on the first electrode, a second piezoelectric layer having a second c-axis orientation over the first piezoelectric layer, and a second electrode on the second piezoelectric layer. The first and second piezoelectric layers are made of respective different piezoelectric materials. The FBAR can be set to have different resonance frequencies by selecting the first and second c-axis orientations to be respectively the same or different. The high and low frequency range of the FBAR can thus be extended.

Abstract: A device capable of extending a foot end of a ladder includes a box tube section with an elongated hole, a long engaging plate with an elongated hole and a plurality of inserting teeth, a short engaging plate with a central fixing hole, two pairs of engaging slots and an engaging nut, and a knob head bolt. The knob head bolt passes through the elongated holes, and the central fixing hole to be tightened to the engaging bolt via a rail of the ladder. The long and short engaging plates are disposed in the box tube section to face to each other. The knob head bolt is loosened or tightened to cause two pairs of the inserting teeth disengaging or inserting into the engaging slots for the box tube section being operated to extend a distance outward the rail stably and safely.

Abstract: A mobile deixis device includes a camera to capture an image and a wireless handheld device, coupled to the camera and to a wireless network, to communicate the image with existing databases to find similar images. The mobile deixis device further includes a processor, coupled to the device, to process found database records related to similar images and a display to view found database records that include web pages including images. With such an arrangement, users can specify a location of interest by simply pointing a camera-equipped cellular phone at the object of interest and by searching an image database or relevant web resources, users can quickly identify good matches from several close ones to find an object of interest.

Abstract: A method and apparatus for washing a dog by means of agitation. The agitation is accomplished by placing the dog in a whirlpool of warm water, which periodically reverses direction, therefore creating the same type of scrubbing effect as in a home washing machine, but without a solid agitator shaft in the middle or any solid bodies touching the dog. Soap and conditioner may be dispensed into the whirlpool at various times during the process to assist in further cleaning and conditioning depending on which type of cleaning cycle the operator chooses on a control panel.

Abstract: A method of making a magnetorestrictive sensor involves the deposition of a magnetorestrictive strip over a substrate, the deposition of an insulating layer over the magnetorestrictive strip, the etching of barber pole windows through the insulating layer, the deposition of a conductive material over the insulating layer and into the barber windows, and the etching away of the conductive material between the barber pole windows so as to form barber poles. In this manner, the formation of the barber poles is controlled by the windows formed in the insulating layer.

Abstract: A hinge on a ladder comprises outer casing pair, inner casing pair, a fixing plate with a shaft and three lock pins, a central rivet pin, and a button knob. The outer casing pair and the inner casing pair are pivotally engaged to each other in such a way that the circular plate portions on the casing pairs facially contact with one another. When the locating holes on the outer casing pair align with three specific ones of nine locating holes on the inner casing pair, the three lock pins are pushed toward the outer casing pair and to pass through the aligned locating holes and perform a locking position. When the button knob is pressed toward the outer casing pair against the restoring force of the spring, the three lock pins move away the locating holes. Therefore, the elongated projection ends of the three lock pins fit with the elongated slots on a half piece of outer casing pair to perform an unlocked position.
