Surgical systems and methods for administering an ablation treatment and other therapeutic or diagnostic protocols to a patient tissue involve a flexible stabilizer mechanism having an inner recess and an ablation mechanism coupled with the stabilizer mechanism.

A gasketed pipe joint including a dual-functional, composite gasket, which in addition to forming a seal between a pipe bell and a spigot provides a molding surface for forming a bent retainer in the hub of the pipe or fitting. The dual-functional composite gasket comprises a first axially disposed portion formed of a non-elastomeric, substantially rigid, substantially non-resilient plastic material and has a first leading edge and a first trailing edge, and a second axially disposed portion, adjacent the first axially disposed portion, formed of an elastomeric material. Preferably, the gasket comprises a major portion of the non-elastomeric, substantially rigid, substantially non-resilient plastic and a minor portion of the elastomeric material.

The present invention aims to simply showing to the user what operations are available with the combination of the disc medium type, the application format of the data recorded/to be recorded on the disc medium, and the information processing apparatus being used by the user.

The present invention displays the medium type/the application format type, etc. on the display or the like when the disc medium is loaded/the disc medium is played back/data is recorded on the disc medium/the disc medium is ejected. This improves the user's recognition of the operations, and the comfort thereof.

A solar power plant having a plurality of receiver panels mounted in a circular fashion about a solar receiver. Each receiver panel includes a plurality of tubes that terminate at each end at a header. To eliminate the presence of gaps between the tubes of adjacent receiver panels the headers are staggered or beveled. In the staggered configuration the headers of adjacent receiver panels are located in different elevations so that the headers of adjacent receiver panels may overlap each other, thus allowing the headers and tubes of adjacent receiver panels to be positioned closer together to eliminate gaps between the tubes of adjacent panels. In the beveled configuration the headers are angled such that the terminal ends of adjacent headers are parallel and positioned in a closely abutting relationship, resulting in the absence of gaps between adjacent headers and tubes.

Various embodiments of drug delivery devices and methods of assembling such devices are provided. In one embodiment, a drug delivery device for dispensing medicament comprises a medicament cartridge, wherein the cartridge comprises (i) a distal end, (ii) a proximal end that is opposite the distal end along a body axis of the cartridge, and (iii) a movable piston arranged substantially at the proximate end of the cartridge. The drug delivery device further comprises a piston rod having a distal end for axially moving the piston in the distal direction during dispensing of a set dose of medicament, wherein a relative axial distance between the distal end of the piston rod and a proximal face of the piston is set during assembly of the drug delivery system. The relative axial position between may be set such that the piston rod and the proximal face of the piston abut each other.

The present invention is directed to a method of forming an FeRAM integrated circuit, which includes performing a capacitor stack etch to define the FeRAM capacitor. The method comprises etching a PZT ferroelectric layer with a high temperature BCl₃ etch which provides substantial selectivity with respect to the hard mask. Alternatively, the PZT ferroelectric layer is etch using a low temperature fluorine component etch chemistry such as CHF₃ to provide a non-vertical PZT sidewall profile. Such a profile prevents conductive material associated with a subsequent bottom electrode layer etch from depositing on the PZT sidewall, thereby preventing leakage or a “shorting out” of the resulting FeRAM capacitor.

Communication systems are described that use geometrically shaped constellations that have increased capacity compared to conventional constellations operating within a similar SNR band. In several embodiments, the geometrically shaped is optimized based upon a capacity measure such as parallel decoding capacity or joint capacity. In many embodiments, a capacity optimized geometrically shaped constellation can be used to replace a conventional constellation as part of a firmware upgrade to transmitters and receivers within a communication system. In a number of embodiments, the geometrically shaped constellation is optimized for an Additive White Gaussian Noise channel or a fading channel. In numerous embodiments, the communication uses adaptive rate encoding and the location of points within the geometrically shaped constellation changes as the code rate changes. One embodiment of the invention includes a transmitter configured to transmit signals to a receiver via a communication channel, wherein the transmitter, includes a coder configured to receive user bits and output encoded bits at an expanded output encoded bit rate, a mapper configured to map encoded bits to symbols in a symbol constellation, a modulator configured to generate a signal for transmission via the communication channel using symbols generated by the mapper. In addition, the receiver includes a demodulator configured to demodulate the received signal via the communication channel, a demapper configured to estimate likelihoods from the demodulated signal, a decoder that is configured to estimate decoded bits from the likelihoods generated by the demapper. Furthermore, the symbol constellation is a capacity optimized geometrically spaced symbol constellation that provides a given capacity at a reduced signal-to-noise ratio compared to a signal constellation that maximizes d_min.

A speech media transcription system comprises a playback device arranged to play back speech delimited in segments. The system is programmed to provide, for a segment being transcribed, an adaptive estimate of the proportion of the segment that has not been transcribed by a transcriber. The device is arranged to play back that proportion of the segment, optionally after having already played back the entire segment. Additionally, a segmentation engine is arranged to divide speech media into a plurality of segments by identifying speech as such and using timing information but without using a machine conversion of the speech media into text or a representation of text.

Communication systems are described that use signal constellations, which have unequally spaced (i.e. ‘geometrically’ shaped) points. In many embodiments, the communication systems use specific geometric constellations that are capacity optimized at a specific SNR. In addition, ranges within which the constellation points of a capacity optimized constellation can be perturbed and are still likely to achieve a given percentage of the optimal capacity increase compared to a constellation that maximizes d_min, are also described. Capacity measures that are used in the selection of the location of constellation points include, but are not limited to, parallel decode (PD) capacity and joint capacity.
