Abstract: Provided herein are apparatuses for fabricating wire current collector and/or interconnect assemblies for solar cells. In certain embodiments, the wire assemblies include uniformly pitched serpentine wires. According to various embodiments, the apparatuses include opposing re-circulating chain link assemblies having uniformly pitched posts and a wire weaving assembly configured to weave wire around the re-circulating posts. Also provided are methods of fabricating solar cells including the wire assemblies.

Abstract: A method of performing a signal enhancement operation on a digital input signal is described. The method produces a best estimate of a true signal which the digital input signal is assumed to represent. The method involves deriving a plurality of candidate mappings, each defining a mapping between the signal domain of the digital input signal and an alternative optimisation domain, each signal in the signal domain corresponding to a set of optimisation parameters in the optimisation domain. For each candidate mapping, an indicator of the quality of the candidate mapping is calculated an a set of optimisation parameters in the optimisation domain of the candidate mapping is generated, the set of optimisation parameters re resenting an enhanced signal in that domain. The highest-quality mapping is then selected in dependence on the calculated indicators, and the set of optimisation parameters generated for the selected mapping is selected.

Abstract: A magnetically-activatable sheet product comprising a pair of laminated outer sheets between which is a magnetic layer comprising magnetically-activatable particles in a binder matrix, at least one layer applied to the outward facing surface of one of the outer sheets, said layer comprising a pigment and a binder; and a thermal coating or a thermal ink applied to said layer.

Abstract: A magnetically-activatable sheet product is provided comprising a pair of laminated outer sheets at least one of which is provided with a pigment/binder primer coat on its inward facing surface, between which is a magnetic layer comprising magnetically-activatable particles in a binder matrix, the outer sheets having sufficient opacity to mask the appearance of the magnetic layer.

Abstract: A magnetically-activatable sheet product is provided comprising a pair of laminated outer sheets between which is a magnetic layer comprising magnetically-activatable particles in a binder matrix, the outer sheets having sufficient opacity to mask the appearance of the magnetic layer, at least one of the outer sheets being provided on its outward facing surface with a coating which comprises either microcapsules containing a solution of at least one chromogenic material, or dispersed droplets containing at least one chromogenic material in a pressure-rupturable matrix, or a colour developer composition, or both microcapsules containing at least one chromogenic material and also a colour developer.

Abstract: A sealable connector comprises a first connector portion, a second connector portion adapted to engage the first connector portion, a compliant material disposed between the first and second connector portions, and a fastening mechanism that secures the first connector portion to the second connector portion, such that a force applied upon the compliant material by the respective first and second connector portions can be adjusted. The fastening mechanism allows a single connector to be utilized for a variety of applications and allows the connector to be adequately sealed regardless of the manufacturing tolerances of the compliant material.
