Abstract: The present invention provides synthetic fibres with advantageous properties such as high tensile strength and which can be produced by recombinant biotechnological means. The invention also provides the constituent components from which the fibres are assembled, along with fabrics formed from the synthetic fibres. Items comprising the fibres and fabrics of the invention are also included.

Abstract: A contact unit for an animal training system and a method for producing the same. The contact unit includes at least one base portion formed from a moldable electrically non-conductive material and at least two contact probes formed from a moldable electrically conductive material. At least one contact probe is provided in each base portion. The contact probes include integral probe tips that extend outward from the at least one base portion. The contact unit is releasably mountable to a controller housing. A collar is used to mount the controller housing and the contact unit around the neck of the animal to maintain the probe tips in contact with the skin of the animal.

Abstract: A flexible earhook for positioning an earphone adjacent a wearer's ear, the earhook including a mounting element capable of being provided with the earphone. The mounting element may be substantially annular. The earhook further includes a hook element comprising a material capable of being contoured and thereafter maintaining its shape. The hook element may comprise a wire. The hook element and the mounting element may be connected such that the flexible earhook can be used on either ear.

Abstract: A headband for reversible mounting of headsets, wherein the headset can be used on either side of the wearer's head. The headband may include two adjustably connected portions, for adapting to the wearer's head. On one side, the headband has a fitting for a headset. The fitting may include a plurality of tabs surrounding a substantially circular cavity. The headset may be mounted to the headband by fitting at least a part of the headset inside the cavity, wherein the headset is held in place by the tabs. The tabs may be arranged to allow the headset to extend therebetween, and they may allow the headset to be adjusted as desired by the wearer.

Abstract: A microphone holder includes a housing comprising a base portion having a first aperture therein and sidewall portions disposed on the base to provide the housing with a microphone receiving cavity region. A cover, having a second aperture therein, is disposed over the cavity region of the housing and a baffle is disposed a predetermined distance over a first surface of the cover in the region of the second aperture.

Abstract: An interface assembly for providing an electrical and mechanical interface between a headset and a headset amplifier, includes a transmit signal path for receiving a signal from the headset microphone and for providing an output signal having electrical characteristics compatible with the headset amplifier. The interface assembly also includes a receive signal path for receiving a signal from the headset amplifier and for providing a signal having electrical characteristics compatible with the headset coupled thereto. Compatibility from headset to headset amplifier may be achieved by adjusting one or more characteristics including but not limited to the frequency response, input/output impedance matching, level adjustment and RFI suppression.

Abstract: An adjustable headset headband including a resilient band of a shape and size to fit over the head of a wearer. The band has a first end and a second end and a positioning member fixedly attached adjacent the first end. The headband also includes a housing having a first end and a second end. The positioning member is movably mounted within the housing such that the second end of the housing is oriented nearest the second end of the band. The housing includes a plurality of depressions linearly arranged within the housing from the first end of the housing to the second end of the housing, each depression of the plurality of depressions having a shallower depth than the preceeding depression. The positioning member releasably engages one of the plurality of depressions so as to maintain the positioning member at a predetermined portion within the housing.
