Abstract: A probe for detecting cancerous tissue, the probe including an illuminator, an optical spectrum analyzer, and an indicator for indicating whether cancerous tissue has been detected in reflected spectrum analyzed by the optical spectrum analyzer. A method for detecting cancerous tissue, the method including providing a probe including an optical spectrum analyzer, placing the probe to include tissue-to-be-tested within a Field-Of-View (FOV) of the spectrum analyzer, optically illuminating the tissue-to-be-tested, analyzing light reflected from the tissue-to-be-tested, and determining whether or not cancerous tissue is detected in the FOV. Related apparatus and methods are also described.

Abstract: A fast sort engine may perform a Radix sort directly on a data elements array and a monotonic function numerical value array. The Radix sort may include use of buckets which may contain elements instead of integers and may use a monotonic value corresponding to each data element in the data elements array to determine to which bucket the data element will be assigned. The fast sort engine may then sort the data elements array directly as it sorts the monotonic function values array. Permutations made to the monotonic function numerical values array are made to the data elements array as well.

Abstract: A method of sorting an array of data elements, the method includes assigning values associated with a monotonic function to the data elements, and sorting the array of data elements by sorting the monotonic function values using a least significant digit (LSD) Radix sort.

Abstract: Constant current power supply arrangements can charge a capacitor with a constant current and are suitable as power supplies for laser diodes. A power supply for a laser diode comprises: a variable voltage power supply, a load path for carrying a laser diode, a shunt path connected in parallel with the load path, a current draining element for switching the shunt path, the current draining element being associated via a first feedback element with the variable voltage power supply such that current drained by the current draining element provides first feedback control of a voltage level of the variable voltage power supply, and a voltage operated second feedback element associated with both the load path and the shunt path to provide second feedback control of the current draining element to drain current via the current draining element in response to current changes at the load.

Abstract: A load deformable bicycle seat comprising a unique substantially flat posterior body section (PS) on which the rider sits, a unique load deformable elongated hollow nose section (NS) of the seat (20). The posterior section (PS) of the seat supports and is designed to promote pressure distribution around the ischael tuberosities. The seat surface is substantially flat or shaped slightly concave to avoid pushing into the perineal region of the groin. The nose (NS) comprises an integrated hollow tubular piece of deformable plastic, rubber, or other material having a rounded and sealed anterior portion (21).
