Network based multiple sensor and control device with temperature sensing and control

A multifunction sensor device which provides various transducer functions including means for performing temperature sensing, humidity sensing, ambient light sensing, motion detection, thermostat functions, switching functions, load switching and dimming functions, displaying actual and set temperature values, displaying time of day values and a means to put the device in an on, off or auto mode. The device has utility in environments such as that found in offices, schools, homes, industrial plants or any other type of automated facility in which sensors are utilized for energy monitoring and control, end user convenience or artificial or natural cooling, heating and HVAC control. The device can be used as a switch or dimmer, sensor or thermostat as well as to adjust and control all natural and artificial lighting, temperature and humidity devices. Key elements of the invention include overcoming the difficulty of mounting diverse sensors or transducers within the same device or housing; permitting these various sensors to exist in a single package that can be mounted to a wall in a substantially flush manner; and eliminating the requirement of an air flow channel in the device, thus minimizing any adverse effects on the motion detecting element or sensor as well as providing built in partial hysteresis. The device may include additional transducers or sensors and is constructed such that the temperature and humidity sensors are neither exposed to the flow of air in a room or area nor in an airflow channel whereby a chimney effect may occur. The device can transmit and receive real time data, relative data and actual discrete data in addition to switching and controlling loads locally or remotely. An embodiment utilizing airflow channels to direct air over the temperature and humidity sensors is also disclosed.

System for long-term remote medical monitoring

A system for long-term remote medical monitoring is especially suitable for the medical supervision of astronauts onboard a space station. The system includes at least one autonomous sensor unit (SU) with a sensor (1) and transmit/receive electrodes (2) connected to a microchip (3) and mounted on a carrier (4) in the form of an adhesive bandage that can easily be applied to the skin of the subject astronaut (11). The system further includes a body transceiver (10) that is worn on the body of the subject and acts as a centralized transmitting and receiving unit, and a portable data logger (12). Medical data such as the pulse rate and the like, as well as environmental data such as the ambient surrounding air temperature, are sensed by respective allocated sensor units (SU) and transmitted from the sensor units as electrical signals via the skin and other body tissues of the subject (11) to the body transceiver (10). From the body transceiver (10), the data signals are further transmitted, for example by a radio or infrared transmission, to the data logger (12), where the data can be recorded, displayed, processed, or further transmitted via a satellite (14) to a base station (13) or a ground-based facility such as a hospital (15). Polling signals are also transmitted from the body transceiver (10) to the sensor units (SU) in a wireless manner through the skin and other body tissues of the subject.

Smokable rod for a cigarette

InactiveUS20050066986A1Not easily dislodgedNot overly flakeyTobacco preparationCigar manufactureEngineeringTobacco smoke
A smokable rod for a smoking article, such as a cigarette, possesses a co-axial or concentric construction. A longitudinally extending inner core of tobacco cut filler is positioned within a smokable rod. The outer material that circumscribes the inner core in an annular fashion is composed of a tobacco material treated with an optional burn suppressing agent, and the outer material acts as a substrate for an aerosol forming material. A preferred aerosol forming material is glycerin. An outer paper wrapper circumscribes the length of the smokable rod, and another paper wrapping material also can circumscribe the inner core material. In use, one end of the smokable rod is lit. When the opposite end of the smokable rod is drawn upon, an aerosol composed of tobacco smoke, thermal decomposition products of tobacco, and volatilized aerosol forming material, is provided. Alternatively, a smokable rod can be provided by positioning the tobacco cut filler in the outer annular region, and by constructing the inner core portion using the tobacco material treated with aerosol forming material and an optional burn suppressing agent. Alternatively, a smokable rod possesses a single blend of smokable materials; at least a portion the smokable material being a tobacco material carrying a relatively high amount of aerosol forming material; and optionally at least a portion of the smokable material being in intimate contact with a burn suppressing agent. A filtered cigarette can be produced by attaching a filter element to one end of any of those smokable rods.

The cutting head assembly is structured to be detachably coupled to the positioning ring by a coupling member which permits movement of the cutting head assembly relative to the positioning ring along the generally arcuate path, but maintains sufficient engagement therebetween to ensure that smooth, steady, driven movement is maintained.

Method and apparatus for patterned plasma-mediated laser trephination of the lens capsule and three dimensional phaco-segmentation

System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.

Bone fastener and instrument for insertion thereof

A bone member fastener for closing a craniotomy includes a cap and a base interconnected by a narrow cylindrical collar. The cap has an externally threaded stud that screws into an internally threaded bore of the collar, thereby allowing the cap and base to be brought into clamping engagement against the internal and external faces of a bone plate and surrounding bone. In a particularly disclosed embodiment, the base of the fastener is placed below a craniotomy hole with the collar projecting into the hole, and the stud of the cap is screwed into the bore of the base from above the hole to clamp a bone flap against the surrounding cranium. This device provides a method of quickly and securely replacing a bone cover into a craniotomy. The distance between the cap and base can be selected by how far the threaded stud of the cap is advanced into the internally threaded collar. The fastener is therefore adaptable for use in several regions of the skull having various thicknesses. An insertion tool with a long handle permits safe and convenient placement of the base between the brain and the internal face of the bone plate. Some disclosed embodiments of the fastener have a cap and base that conform to the curved surface of the skull, for example by having an arcuate shape or flexible members that conform to the curvature of the bone plate and surrounding cranial bone as the fastener is tightened.

Methods and devices for directionally ablating tissue

High density integrated circuit packaging with chip stacking and via interconnections

Chip stacks with decreased conductor length and improved noise immunity are formed by laser drilling of individual chips, such as memory chips, preferably near but within the periphery thereof, and forming conductors therethrough, preferably by metallization or filling with conductive paste which may be stabilized by transient liquid phase (TLP) processes and preferably with or during metallization of conductive pads, possibly including connector patterns on both sides of at least some of the chips in the stack. At least some of the chips in the stack then have electrical and mechanical connections made therebetween, preferably with electroplated solder preforms consistent with TLP processes. The connections may be contained by a layer of resilient material surrounding the connections and which may be formed in-situ. High density circuit packages thus obtained may be mounted on a carrier by surface mount techniques or separable connectors such as a plug and socket arrangement. The carrier may be of the same material as the chip stacks to match coefficients of thermal expansion. High-density circuit packages may also be in the form of removable memory modules in generally planar or prism shaped form similar to a pen or as a thermal conduction module.
