Abstract: Various embodiments for switching functionality of a graphical user interface (GUI) pointer input device are provided. A first gesture pattern is configured. The first gesture pattern, when performed, enables a predetermined function of the input device. The predetermined function substitutes for a default function of the input device. The enabling of the predetermined function is indicated to a user on the GUI. A second gesture pattern is configured. The second gesture pattern, when performed, cancels the predetermined function of the input device and enables the default function.

Abstract: A calculator for use in a maximum likelihood detector, including: a receiver for receiving convolution encoded data which may include noise; first calculator for calculating a first component of a first path metric difference between two possible sequences of states corresponding to the convolution encoded data, the two sequences each having a length equal to a constraint length of the convolution encoded data, and the two sequences starting at a same state and ending at a same state, adapted to calculate the first component using the convolution-encoded data and using convolution encoding parameters of the convolution-encoded data, wherein the first component is independent of the two sequences; and second calculator for calculating a second component of the first path metric difference using the two sequences, wherein the second component is independent of the convolution encoded data; and using the first and second components to obtain the first path metric difference.

Abstract: A strong, lightweight, soft, pliable, perspiration absorbent, economically disposable, foldable to a small packageable size, and reusable, sweatband (15) formed from a unitary body member comprising a perspiration absorbing pad (4) with drain channel (5) and a perspiration absorbing see through removable wiping towel/veil/windscreen (8) which can be protected from perspiration by a removable perspiration shield (14) provided in the pocket (7) of the sweatband to prevent the removable wiping towel (8) from becoming wet from perspiration if the wearer prefers not to have the wiping towel wet. Money, identification, packaged antimicrobial wipes and other items may also be carried in the sweatband pocket (7). The folded, porus, see through, removable wiping towel/veil/windscreen (8), can be easily removed by one hand from the sweatband through a access opening (12) located on the front face of the sweatbands second elongated envelope (2).
