This invention describes feed supplement, and processes which increase the amount of essential fatty acids in the milk, eggs, meat and other by-products from animals including dairy cattle, beef cattle, goats and poultry. The food supplement described herein includes specific fish meal, fish oil, algae or plant dietary supplements combined with a natural ingredient/coating mixture, which can be either talc, clay or combinations; or mixtures of talc or clay with flax sprout powder to achieve enha...

A layered switch assembly permits more than one electric circuit function to be obtained from each of a set of switches used to control electric circuit functions such as the operation or adjustment of seats, mirrors or other components in an automotive vehicle passenger compartment. A group of switches for operator control is embedded in an armrest, console, or the like. Overlying the discrete switches are two or more flexible sheet or membrane layers for selective activation of one or more of ...

A key switch includes a front cover formed with a cursor key hole. In the front cover, a first rib is formed on a first support wall and a second rib is formed on a second support wall. Accordingly, when a cursor key part disposed in the cursor key hole is pressed, it can be restrained against motion in a shorter side direction. The operationality of a cursor key can be improved, which allows a correct operation.

There is provided herein a system and method for obtaining measurements of radiation exposure in real time using OSL and for obtaining improved accurate OSL measurements over a greater range of radiation exposures. In a preferred embodiment a signal-versus-dose response is obtained from an OSL dosimeter that is linear over all doses and does not exhibit saturation effects. The desired response is preferably calculated from the measured OSL-versus-time response from a suitable dosimeter obtained ...

A voltage buffer for capacitive loads isolates the load from the feedback loop. Using a variation of a follower arrangement, a second transistor outside of the feedback loop introduced. The current to the load is supplied through the second transistor, which is connected to have the same control gate level as the transistor in the feedback loop and provide an output voltage based on the reference input voltage. The output voltage is dependent upon the input voltage, but the load is removed from ...

A current source DAC has calibration of the current sources used for providing the analog output. There are two outputs, one of which provides the output current or else a differential output is provided. The calibration is cyclic and the current source outputs switched to the output terminals are selected as a function of the point within the calibration cycle. The current stage of the cyclic calibration process is thus taken into account in the D/A conversion. For example, the average time sin...

A micro electromechanical switchable capacitor is disclosed, comprising a substrate, a bottom electrode, a dielectric layer deposited on at least part of said bottom electrode, a conductive floating electrode deposited on at least part of said dielectric layer, an armature positioned proximate to the floating electrode and a first actuation area in order to stabilize the down state position of the armature. The device may furthermore comprise a second actuation area. The present invention provid...

A system and method of calibrating a digital-to-analog converter (DAC) such as a resistor string DAC that reduces costs by making more efficient use of integrated circuit chip area, without requiring analog calibration circuits. The DAC calibration system includes a main DAC to be calibrated, a memory, and calibration logic circuitry for performing arithmetical operations. The memory stores a predetermined number of digital code values in respective memory locations, which are indexed by corresp...

A quartz heater is provided for heating fluids or objects. The heater comprises a member, for example, a quartz glass tubular or non-tubular member, with a low-emissivity conductive coating that produces heat when connected to external power. The fluid can be heated as it passes through the tubular member. If the member is not completely coated, then heat radiates toward the center of the member, pass through its uncoated portion, and then onto objects for heating.

A packaging apparatus has hot air supply mechanisms disposed in association with light-shielding shrinkable films wound on a rolled photosensitive material sheet, for ejecting hot air locally to the light-shielding shrinkable films, and a drive mechanism for relatively rotating the hot air supply mechanisms along an outer circumferential surface of the rolled photosensitive material sheet.
