In an analog-to-digital conversion method for converting a difference signal component representing a difference between a reference component and a signal component in an analog signal to be processed into digital data, in a first process, a signal corresponding to one of the reference component and the signal component is compared with a reference signal for conversion into the digital data. Concurrently with the comparison, counting is performed in one of a down-count mode and an up-count mode, and a count value at a time of completion of the comparison is held. In a second process, a signal corresponding to the other one of the reference component and the signal component is compared with the reference signal. Concurrently with the comparison, counting is performed in the other one of the down-count mode and the up-count mode, and a count value at a time of completion of the comparison is held.

A new pixel in semiconductor technology comprises a photo-sensitive detection region (1) for converting an electromagnetic wave field into an electric signal of flowing charges, a separated demodulation region (2) with at least two output nodes (D10, D20) and means (IG10, DG10, IG20, DG20) for sampling the charge-current signal at at least two different time intervals within a modulation period. A contact node (K2) links the detection region (1) to the demodulation region (2). A drift field accomplishes the transfer of the electric signal of flowing charges from the detection region to the contact node. The electric signal of flowing charges is then transferred from the contact node (K2) during each of the two time intervals to the two output nodes allocated to the respective time interval. The separation of the demodulation and the detection regions provides a pixel capable of demodulating electromagnetic wave field at high speed and with high sensitivity.

A wave-fan comprises a wavy surface, generally sinusoidal in the direction of rotation, which rotates in close proximity to the fins of a heat sink. The wave-plane fan is suitable for use with a flat heat sink, and a wave-ring fan is suitable for use with a cylindrical heat sink. There are no airfoils as in a prior art fan. Instead, the ridges of the wave-fan agitate the air between the fins of the heat sink as each ridge passes, breaking down the boundary layer and effecting good heat flow into the air. In some embodiments of the wave-fan, the outer surfaces are smooth, so it is not a hazard to intruding fingers, so in many applications it may be used without a guard or enclosure. Incidental centrifugal force provides some airflow through the fan to transport the heated air away from the fan. Also, the configuration of the fan tends to keep contamination in the air out of the heat sink fins, so an inlet air filter may not be needed. Because the net airflow through the fan is low, less power is required and it is very quiet.

The wedge-shaped rotary valve is positionable to provide either only cold fluid to the first outlet port, only return fluid to the first outlet port, or blending of the cold fluid and return fluid to the first outlet port.

A beehive includes a column of stacked boxes which open onto each other at their tops and bottoms, with the column bearing a cap at its top and a floor at its bottom. The boxes have access ports for ingress and egress of bees, and the column is suspended above the ground on a support post which bears a pivot such that the column can be tipped from a vertical orientation to a horizontal orientation for easy maintenance. Bars, frames, and/or screens may be hung within and atop the boxes to promote desired comb-building behaviors, with bees tending to build comb downwardly from higher boxes into lower boxes. At desired times, upper boxes bearing honey may be removed from the column and lower boxes bearing brood may be rotated to the top of the column so that the bees continuously propagate down the column.
