摘要:
The invention provides modified molecular beacons detectable by surface enhanced Raman spectroscopy (SERS) and related materials, processes, and methods of use. Examples methods provide for the determination of the presence or absence of a target nucleotide sequence in a sample nucleic acid by (a) providing a detection agent, which agent comprises: (i) a probe comprising a target complement sequence (TCS) being complementary to the target sequence and flanking the TCS, first and second oligonucleotide arms, said first and second oligonucleotide arms forming a stem duplex, and said first arm incorporating a first label moiety being detectable by SERS (e.g. a fluoroscein dye) and said second arm terminating in a second label moiety being detectable by SERS, which second arm further includes a surface seeking group (SSG—e.g. an azo-benzotriazole) capable of promoting association of the second label onto an enhancing surface ii) associated with said probe via said SSG, an enhancing surface, such that said first and second label moieties are in close proximity to each other and to the enhancing surface (b) exposing the sample to the detection agent, (c) detecting hybridisation of the TCS to any target sequence present in the sample by a change in the SERS spectra of said agent.

A reclining chair assembly includes a reclining chair that has a backrest portion and a chair portion for having a user sit therein. A pair of footrests is each disposed on the chair portion of the reclining chair and each of the footrests is positionable in a lowered position or a raised position to raise the respective user's leg. Moreover, the pair of footrests is independently positionable in the raised position to facilitate one of the user's legs to be lifted while the other of the user's legs is not lifted. A pair of lifting units is each in mechanical communication with a respective one of the pair of footrests. Each of the lifting units independently urges the respective footrest into the raised position or the lowered position.

A golf swing teaching device to interpret a golf swing comprising a golf club, where the golf club includes a handle, a shaft and a head; a laser attached to the golf club, where the laser directs a beam parallel to the shaft of the golf club; a reflective indicator mat, where the reflective indicator mat extends between a first end and a second end; a rest toward the first end, where the rest positions a golf ball on the reflective indicator mat; an ideal swing line along a central portion of the reflective indicator mat, where the ideal swing line extends from the first end to the second end; and a plurality of sensors along the reflective indicator mat, where the plurality of sensors detect a path of the beam over the reflective indicator mat and deviation of the beam from the ideal swing line.
摘要:
Commonly, a transient protection filter circuit is integrated between power sources and the circuits that follow to suppress voltage transients. Pre-existing transient protection filters are implemented such that when a transient is detected, transistors in the path become linear regulators. Instead, this invention uses bridge resistors to form a voltage divider to dissipate the extra power. The novelty of this invention is that it protects the load not by dissipating the extra power in front of the load as other transient protection filter circuits do, but by providing energy from the transient to the load through a resistor. This implementation solves the problem of thermal runaway that is commonly caused when transient voltages are filtered by dissipating power within the transistors in the path of the transient and the electric circuits after the transistors.

A prefabricated wall panel has a precast body including at least one decorative design element. In addition, the wall panel includes a mounting element having a first end embedded in the precast body and a second end projecting from the precast body. A groove is formed between the precast body and the second end of the mounting element along a first edge of the precast body. A tongue is formed along a second edge of the precast body opposite the first edge. The tongue and groove cooperate to allow prefabricated wall panels to be more easily installed on a support substrate.
