Device for irradiating tissue

A device for irradiating tissue includes a fluorescent element for receiving pump radiation and responsively emitting radiation having different spectral characteristics than the pump radiation. A redirector receives emitted radiation promulgated in a direction away from a tissue target and redirects the radiation toward the target. The pump radiation may be supplied, for example, by a flashlamp or frequency-doubled neodymium-doped laser. Use of the device provides an inexpensive and effective alternative to conventional dye laser-based systems for various medical therapies, including treatment of vascular and pigmented lesions, tattoo and hair removal, and photodynamic therapy (PDT).

Self-powered cordless mouse

A self-powered computer-pointing device includes a housing and a roller ball accommodated within the housing. At least a portion of the roller ball is exposed through an opening in the housing to allow the roller ball to contact a surface on which the computer-pointing device rests. Movement of the computer-pointing device across the surface imparts rotation of the roller ball. A sensing mechanism senses movement of the roller ball and generates x-y movement signals corresponding to movement of the computer-pointing device across the surface. The sensing mechanism conveys the x-y movement signals to a host computer. A power generating mechanism is coupled to the roller ball and converts rotational movement of the roller ball into electrical energy that is used as power by the computer-pointing device.

Handheld cleaning appliance

A cleaning appliance includes a main body, a filter and an interlock. The main body includes an airflow generator, a separating apparatus separating dirt and dust from an airflow, and a flowpath between the separating apparatus and the airflow generator delimited by a wall. The interlock has a first part located on the filter and a second part located on the main body outside the flowpath, arranged to communicate remotely when the filter is correctly located in the pre-determined position. The interlock is arranged selectively to allow or prevent operation of the airflow generator depending upon the relative separation between the first and second parts. By providing an interlock which has first and second parts which communicate remotely, the second part located on the main body can be isolated from the airflow path so that the second part is not subject to dirt and dust carried by the airflow.

Method for temperature measurement in a household appliance

A method for temperature measurement in a household appliance includes generating a high-frequency electromagnetic excitation wave of a predefined transmit frequency. The transmit frequency is selected from a frequency band including temperature-dependent resonant frequencies that occur in a surface wave device incorporated in a temperature measuring probe and which respectively correspond to temperatures expected at the temperature measuring probe during operation of the household appliance. During a first phase, the excitation wave is wirelessly transmitting to the surface wave device. During a second phase following the first phase, an electromagnetic response wave generated by the excitation wave in the surface wave device is wirelessly transmitting to a processing unit. Signal levels of response signals generated from response waves of different transmit frequencies are measured and compared to determine the current temperature of the surface wave device based on the transmit frequency associated with the highest signal level.

A floating type wave power generation system

A floating type wave power generation system is characterized in that the system consists of eight sets of lever-type floating bodies and a hydraulic energy accumulation converter with the hydraulic pump function. On a floating workbench 7, eight sets of levers 2 and a floating body 1 are connected through supporting hinge bearers 10 and 11; in this way, the highly undulating displacement caused by waves can be converted to relatively lesser displacement of a piston rod 4, and the minor force that the floating body bears can be converted through the lever to the major force on the piston rod. The piston rod drives a hydraulic tank 3 to switch and transmit the hydraulic energy through a connecting oil pipe5, a high-pressure oil pipe6, a hydraulic oil tank and four no-return valves of each set to a hydraulic motor in a hydraulic power generation control chamber 9; in this way the generator is driven to work. The present system can absorb, convert and accumulate the intermittent unstable wave energy in a highly effective way and can buffer the destructive effect of waves. The floating platform can be suitable to different marine space by adjusting the length of an anchor chain 8. And in various sea conditions, kinetic energy and potential energy possessed by waves in the sea surface can be converted and accumulated as hydraulic mechanical energy by utilization of the wave drop; thus the generator is driven to unremittingly provide electric power.

Method to determine tdc in an internal combustion engine

A method and apparatus for accurately determining TTX: in a cylinder of an internal combustion engine. Gas pressure is measured in the cylinder relative to crank angle, giving rise to a curve of gas pressure with crank angle. An offset is found by first computing the angular position of an inflexion point of the compression pressure curve measured as a function of the crank angle, and then computing the offset as the difference between the angular position of a piston in the cylinder and a theoretical value for said angular position of the piston dependent on a known or measured flywheel angle. The value of TDC corrected by the offset is then used to calculate a value of work output such as the indicated Mean Effective Pressure (IMEP) which may be used for diagnostic and / or control purposes.

Coffee machine with a manually operated lid of an inlet for special coffee and a method for monitoring the position of this lid

A coffee machine with an integrated coffee grinder and a powder chute, which serves the purpose of feeding ground coffee from the coffee grinder to a movable brewing cylinder, has an inlet with a manually operated lid for already ground special coffee. A sensor detects the position of the lid. The detection signal of the sensor is passed on to a processor controlling the coffee machine, and the signal is used to differentiate between a normal operating mode and an operating mode for producing special coffee. If the lid is opened for a certain minimum time span, a subsequent coffee preparation cycle in the operating mode for producing special coffee is initialized. Since, to that end, no separate pre-selection is required any longer, the operation of the coffee machine is simplified and the susceptibility to problems is reduced.
