Eyeglasses with wireless communication features

A microphone, transmitter, speaker, receiver, and power source, all mounted to an eyeglasses frame, for sending and receiving signals wirelessly to and from a remote cell phone or other electronic device. The microphone and the transmitter can be mounted to extension arms that can be extended, pivoted, or otherwise moved to a position for use, and then moved to a stored position when not in use. Alternatively, the microphone, transmitter, speaker, receiver, and power source, can be mounted onto a clip-on or other attachment member that mounts onto a conventional eyeglasses frame, or to a hat or other article worn on the head.

Method and apparatus of a self-configured, model-based adaptive, predictive controller for multi-zone regulation systems

A control system simultaneously controls a multi-zone process with a self-adaptive model predictive controller (MPC), such as temperature control within a plastic injection molding system. The controller is initialized with basic system information. A pre-identification procedure determines a suggested system sampling rate, delays or “dead times” for each zone and initial system model matrix coefficients necessary for operation of the control predictions. The recursive least squares based system model update, control variable predictions and calculations of the control horizon values are preferably executed in real time by using matrix calculation basic functions implemented and optimized for being used in a S7 environment by a Siemens PLC. The number of predictions and the horizon of the control steps required to achieve the setpoint are significantly high to achieve smooth and robust control. Several matrix calculations, including an inverse matrix procedure performed at each sample pulse and for each individual zone determine the MPC gain matrices needed to bring the system with minimum control effort and variations to the final setpoint. Corrective signals, based on the predictive model and the minimization criteria explained above, are issued to adjust system heating/cooling outputs at the next sample time occurrence, so as to bring the system to the desired set point. The process is repeated continuously at each sample pulse.

Dental implantation system and method

Drilling of an implant shaft is carried out with a handpiece tool whose location and angular orientation with respect to a radiographic working guide is updated in real time with respect to the radiographic working guide and anatomical structures of the patient, free of viewing obstructions. Prior to the drilling, the radiographic working guide is fitted to a particular patient. Real-time imaging support is provided on a display of a computer, wherein the radiographic workpiece guide includes a plurality of fiducial markers that define a substantially planar reference surface of the radiographic workpiece guide. The radiographic workpiece guide also includes an alignment structure located a predetermined distance from a pilot hole proximate the work site. The image is updated based on an initial radiographic scan and updated position information from the handpiece tool as to location and angular orientation of the handpiece tool relative to the workpiece guide.

Endodontic rotary instruments made of shape memory alloys in their martensitic state and manufacturing methods

A method for manufacturing a non-superelastic rotary file comprising the steps of: providing a superelastic rotary file having an austenite finish temperature; and heating the superelastic rotary file to a temperature of at least about 300° C. for a time period of at least about 5 minutes to alter the austenite finish temperature thereby forming the non-superelastic rotary file; wherein the altered austenite finish temperature of the non-superelastic rotary file is greater than about 25° C.
