Abstract: A sodium electrochemical cell that supports a current density at the negative electrode of at least 500 ?A/cm2, the electrochemical cell comprising (i) a negative electrode and (ii) a sodium-ion ionic liquid electrolyte having a sodium-ion concentration that is no less than 75% of its saturation limit in the electrolyte, wherein the negative electrode has a solid-electrolyte interphase (SEI) layer formed as a result of the electrochemical cell having undergone a polarisation cycle.

Abstract: A device and process in which a single continuous depositional layer of a polycrystalline photoactive material is deposited on an integrated charge storage, amplification, and readout circuit with an irregular surface wherein the polycrystalline photoactive material is comprised of a II-VI semiconductor compound or alloys of II-VI compounds.

Abstract: A radiological image sensor has an electronic substrate and an imaging chip held within a housing, the imaging chip having electronics that create a dead space, with a cable attached to the housing at a cable button connector, the dead space being at a short distal side of the generally rectangular sensor opposite the short mesial side at which the cable exits the cable button connector. The mesial side of the sensor either does not have a dead space created by electronics of the imaging chip or the dead space found on the mesial side of the sensor is less than approximately 4 mm, and, preferably, approximately 2 mm or less. The cable can be a flat cable with a length of approximately one meter or less that can be connected to a round cable.

Abstract: A universal dental digital sensor holder has a bite block connected to a rod that has a connector which is used to flexibly attach a sensor holder so as to allow rotational movement of the sensor relative to the bite block and multiple sensor holders are removably connected to the connector so that they can be used to obtain different radiographic projection views due to their differing configurations for holding the intraoral sensor in the patient's mouth. The bite block can have an opening formed in it fitted with a sleeve to allow access to a tooth located beneath the opening in the patient's mouth. A cable protector can be formed in the rod adjacent an anterior bite surface so that an intraoral sensor cable can be held adjacent the rod and at least partially protected from one or more teeth biting the anterior bite surface.

Abstract: A variable aperture X-ray collimating device that fits over existing intraoral radiographic sensor positioners enables clinicians to provide radiation protection for their patients while allowing the flexibility to accommodate various commercially available positioning kits. In addition, the variable aperture allows for easy accommodation of various sensor sizes.

Abstract: A system is described for obtaining intraoral radiographic images using an anatomically conforming sensor and a method is described for correcting the projective distortions caused by the inclination of the plane of the imaging sensor relative to the x-ray beam. The purpose of the described sensor system is to reduce patient discomfort as compared to conventional planar intra-oral x-ray sensors, which tend to impinge on sensitive tissues within the oral cavity. An additional purpose of the described system is to allow for better coverage of the subject by allowing the sensor to fit closer against the surrounding tissues.

Abstract: A caries detection system and method for quantifying a probability of lesions existing in tissues are presented. Digital X-ray images are segmented and further processed to generate feature statistics inputs for a neural network. The feature statistics include colinearity measurements of candidate lesions in different tissue segments. The neural network is trained by back propagation with an extensive data set of radiographs and histologic examinations and processes the statistics to determine the probability of lesions existing in the tissues.
