Abstract: LED epitaxial layers (n-type, p-type, and active layers) are grown on a substrate. For each die, the n and p layers are electrically bonded to a package substrate that extends beyond the boundaries of the LED die such that the LED layers are between the package substrate and the growth substrate. The package substrate provides electrical contacts and conductors leading to solderable package connections. The growth substrate is then removed. Because the delicate LED layers were bonded to the package substrate while attached to the growth substrate, no intermediate support substrate for the LED layers is needed. The relatively thick LED epitaxial layer that was adjacent the removed growth substrate is then thinned and its top surface processed to incorporate light extraction features.

Abstract: A method is disclosed for providing early detection, classification, and reporting of health-related events in a population. The method includes capturing sets of specific emergency room patient information from a subset of the population as the patient information is first electronically entered into, for example, an electronic medical record (EMR). The patient information is pre-processed, transmitted to and stored in a central database in a central computer facility. The patient information is sorted and analyzed by the central computer facility to detect any health-related events in the population and to generate corresponding alerts. The alerts are electronically reported to designated authorities such as health officials and other government authorities such as the CDC.

Abstract: A semiconductor light emitting device includes an n-type region, a p-type region, and light emitting region disposed between the n- and p-type regions. The n-type, p-type, and light emitting regions form a cavity having a top surface and a bottom surface. Both the top surface and the bottom surface of the cavity may have a rough surface. For example, the surface may have a plurality of peaks separated by a plurality of valleys. In some embodiments, the thickness of the cavity is kept constant by incorporating an etch-stop layer into the device, then thinning the layers of the device by a process that terminates on the etch-stop layer.

Abstract: A semiconductor light emitting device includes an in-plane active region that emits linearly-polarized light. An in-plane active region may include, for example, a {11{overscore (2)}0} or {10{overscore (1)}0} InGaN light emitting layer. In some embodiments, a polarizer oriented to pass light of a polarization of a majority of light emitted by the active region serves as a contact. In some embodiments, two active regions emitting the same or different colored light are separated by a polarizer oriented to pass light of a polarization of a majority of light emitted by the bottom active region, and to reflect light of a polarization of a majority of light emitted by the top active region. In some embodiments, a polarizer reflects light scattered by a wavelength converting layer.

Abstract: A photonic crystal structure is formed in an n-type region of a III-nitride semiconductor structure including an active region sandwiched between an n-type region and a p-type region. A reflector is formed on a surface of the p-type region opposite the active region. In some embodiments, the growth substrate on which the n-type region, active region, and p-type region are grown is removed, in order to facilitate forming the photonic crystal in an an-type region of the device, and to facilitate forming the reflector on a surface of the p-type region underlying the photonic crystal. The photonic crystal and reflector form a resonant cavity, which may allow control of light emitted by the active region.

Abstract: The invention is a normalized scoring method and apparatus for the patient care departments of a health care facility having more than one scored patient care department. The scoring method can be used, for example, to direct additional resources to departments that are less well staffed or have fewer available beds or other patient receiving areas than other departments, relative to need. For each scored health care department, scores are preassigned to different numbers of available beds or other patient receiving areas and to different staffing levels in the department. Different departments are independently scored, so the same number of available workers or the same number of available beds may be preassigned different scores in two different departments. An overall score is independently determined for each health care department by adding the patient receiving areas component and the staffing level component, and optionally other factors.

Abstract: Apparatus is provided including an input device, a medical risk database, a data processor, and a communication device. Data entered in the input device, usually by a health care professional, defines a patient data record. The medical risk database associates certain patient data entered into the data record, which increases the risk of a missed medical care opportunity, with additional medical care to address the risk. The communication device responds to the identification of patient data presenting a medical risk by communicating to a health care professional additional medical care selected to identify and take advantage of a medical care opportunity. Templates are also disclosed having “red light green light” indicators that indicate red to prompt consideration of a system and green to indicate it has been considered. A triage template and key information to provide additional information to the diagnosing or treating professional are also provided.

Abstract: A light source is disclosed. In one aspect, a gain region defined by a first and second mirror is provided having a corresponding resonant mode, and an external cavity defined by a third mirror and the second mirror is also provided having a plurality of resonant modes. A birefringent crystal is then disposed within said external cavity for the purpose of controlling the state of polarization.

Abstract: A light source is disclosed for use optical communications systems. In one aspect, a gain region defined by a first and second mirror is provided having a corresponding resonant mode, and an external cavity defined by a third mirror and the second mirror is also provided having a plurality of resonant modes. The second mirror is configured such that one of the external cavity resonant modes is selected. The single channel laser has wavelength precision sufficient to eliminate the need for an external wavelocker, and has an external cavity capable of being directly modulated in a chirp-free manner.
