Abstract: The present invention provides an electrochemical cell comprising an anode; an electrolyte having a solubility for sulfur-containing species of less than 15 mM; a cathode comprising greater than 65 wt. % sulfur, wherein the cathode comprises a carbon-sulfur composite material; and wherein the composite material comprises greater than 65 weight % sulfur based on the total weight of the composite material; and wherein the carbon sulfur composite material is formed from an electroconductive carbon material having an average pore volume of 1.5?3 cm3 g?1 and an average pore diameter of less than 3 nm.

Abstract: An exercise machine comprising: a frame and a support mechanism having a user interactive surface, the user interactive surface comprising a middle section, an upper section), and a lower section disposed vertically below the middle section; the upper and lower sections each including one or both of a visually observable display and a manually actuatable member, the middle section including a surface that is blank; the support mechanism including a mount mechanism adapted to mount a readily portable object in an orientation such that the object overlies entirely within the blank surface of the middle section.

Abstract: The recording device is embodied as a stop watch 10 comprising a watch body 11 having a two-piece strap to secure the stop watch 10 to one hand 20 of its user. On one side, the watch body 11 has a display face 13 and an elongate button 16 for controlling the functioning of the watch 10 and the display on the display face 13. A central region 26 of the watch body 11 is flexible enabling the watch body 11 to be bent in a U or J shape around the hand 20 between forefinger 28 and thumb 27, the two pieces 21, 22 of the strap holding the watch body 11 securely on the hand 20 and wrist 24. With the watch body 11 in the latter described disposition on the hand 20, the button 16 can be actuated by the finger tips 31. Thus, the stop watch 10 can be easily operated one-handed making it particularly suitable for use by athletes.
