A disposable cassette for detecting nucleic acids or performing other assays. The cassette can be inserted into a base station during use. The cassette has numerous features to ensure correct operation of the device under gravity, such as vent pockets for enabling the flow of sample fluid from one chamber to the next when the vent pocket is unsealed. The vent pockets have protrusions to help prevent accidental resealing. The cassette also can have a gasket to ensure free air movement between open vent pockets. A flexible circuit with patterned metallic electrical components disposed on a heat stable material can be in direct contact with fluid in the chambers and has resistive heating elements aligned with the vent pockets and the chambers. The detection chamber, which houses a lateral flow detection strip can have a space below the strip that has sufficient capacity to accommodate an entire volume of the sample fluid entering the detection chamber at a height that enables the fluid to flow up the detection strip by capillary action without flooding or otherwise bypassing regions of the detection strip. The space can also contain detection particles. Recesses in in the cassette channels or chambers can have structures such as ridges or grooves to direct fluid flow to enhance rehydration of lyophilized reagents disposed in the recess. Flow diverters in the chambers can reduce the flow velocity of the sample fluid and increase the effective fluid flow path length, enabling more accurate control of fluid flow in the cassette.

A plurality of pulses each having relatively low energy are consecutively applied to a subject fuse to cause breakdown, wherein the total energy of pulses is set in light of a prescribed breakdown threshold, which is calculated in advance. The subject fuse has a pair of terminals and an interconnection portion that is narrowly constricted in the middle so as to realize fuse breakdown with ease. A pulse generator generates pulses, which are repeatedly applied to the subject fuse by way of a transistor; then, it stops generating pulses upon detection of fuse breakdown. Side wall spacers are formed on side walls of fuses, which are processed in a tapered shape so as to reduce thermal stress applied to coating insulating films. In addition, pulse energy is appropriately determined so as to cause electro-migration in the subject fuse, which is thus increased in resistance without causing instantaneous meltdown or evaporation.

A modem (10) for transmitting a discrete multitone modulated (DMT) signal over a communications channel (H) is disclosed. In the encoding of an input bitstream, unloaded subchannels in the DMT spectrum are assigned signal values so that a trailing portion of each block or frame of the resulting datastream are forced to a known value, for example zero. The known-valued trailing portion of each block provides the effect of a cyclic prefix, without necessitating the prepending of an actual cyclic prefix and incurring the corresponding data rate loss; alternatively, the effect of a cyclic prefix can be augmented by the forcing of the trailing portion of the blocks to known values.

Use of the controller provides a bow which has an inherently balanced draw.

The invention discloses a broadband capacitive feed miniature microstrip paster antenna. A foam dielectric substrate is arranged between a microstrip dielectric substrate and an earth plate and thus the thicknesses of the dielectric substrates are increased; and an equivalent dielectric constant is reduced and a working band width of the antenna is extended. A metal short-circuit surface is loaded at an edge of one side of a radiation paster to form a standing wave structure from an open circuit to a short circuit; and the length of the antenna at the direction perpendicular to the short-circuit surface is a quarter of a wavelength. Slotting is carried out on the radiation paster and the path of an excitation current of the surface of the antenna paster is bent, thereby increasing the effective length of the antenna paster and thus reducing the resonant frequency and realizing miniaturization of the antenna at the another-dimensional dimension. Coupling and feeding are carried out by using a capacitive paster to realize good impedance matching, thereby reducing equivalent quality factors of the antenna and realizing increasing of the operating bandwidth of the antenna. According to the invention, a defect that the existing microstrip paster antenna can not consider the wide frequency band and miniaturization simultaneously can be overcome. The provided antenna has advantages of wide frequency band, low profile, small dimension, light weight, and easy processing.
