Abstract: Disclosed is a label printer for printing labels wound onto a roll that are applied to a carrier tape or that are linerless endless tape labels, having a housing in which a cartridge compartment is formed; a tape cartridge which at least comprises an unwinding mandrel, in which a label roll can be received, and which can be manually inserted into and removed from the cartridge compartment; and a printhead and a driven print roller, wherein the label tape of the label roll can be led between the printhead and the print roller. A spring device and a movable latching holder, which is preloaded into a latching position by a spring force of the spring device, allows the tape cartridge to be latched into the latching holder against the spring force on the insertion and to be unlatched from the latching holder against the spring force on the removal.

Abstract: A device includes a stack of at least two piezoelectric layers configured to propagate a Lamb wave in a mode having an order corresponding to a number of piezoelectric layers of the stack. The stack includes a first piezoelectric layer and a second piezoelectric layer disposed on the first piezoelectric layer. The first piezoelectric layer has a first cut plane orientation, and the second piezoelectric layer has a second cut plane orientation complementary to the first cut plane orientation. The device further includes an interdigitated transducer (IDT) disposed on at least a top surface of the stack or a bottom surface of the stack. In some embodiments, the device is an acoustic resonator. In some embodiments, the device is an acoustic delay line.

Abstract: An acoustic resonator includes a piezoelectric thin film (PTF) disposed on a carrier substrate. The PTF confines a fundamental shear-horizontal (SH0) surface-acoustic wave (SAW) within the PTF. The acoustic resonator includes an input bus line coupled to an input source and a ground bus line coupled to a ground potential. The acoustic resonator includes a first grating reflector disposed at a first end of the PTF and coupled between the input bus line and the ground bus line. The acoustic resonator includes a second grating reflector disposed at a second end of the PTF and coupled between the input bus line and the ground bus line. The acoustic resonator includes interdigital transducers (IDTs) disposed between the first grating reflector and the second grating reflector. Each IDT includes an input electrode coupled to the input bus line, and a ground electrode coupled to the ground bus line.
