Abstract: A method can include, by operation of WLAN circuits, determining an estimated duration for communications of a coexisting wireless circuit (coex communications). In response to at least the medium being free, a CTS-to-self frame can be transmitted having a first duration equivalent to the estimated duration for the coex communications. At an actual start for the coex communications, if the first duration is not sufficient to cover the actual duration, a second CTS-to-self frame can be transmitted with a second duration that extends beyond the first duration sufficient to cover the actual duration. Corresponding devices and systems are also disclosed.

Abstract: A microsurgical instrument that can slide over a surgical suction instrument and comprises a grasper or a micro-scissor for cutting at the distal end, a lever at the proximal end to actuate the jaws of the grasper or the blades of the micro scissor. The disclosed microsurgical instrument may be locked to the surgical suction instrument or may be rotated on the long axis on the surgical suction instrument. The disclosed instrument can be placed by sliding over the surgical suction instrument without the need for disconnecting the surgical suction instrument from the suction hose.

Abstract: A handle for endoscope for two handed micro neurosurgery of the brain comprising adjustable rigid surgical suction, Channel for endoscope, Surgical suction control hole.

Abstract: The present invention discloses a method of improving color quality in anaglyphs. Stereo pair images are viewed using a filter of one primary color on the side corresponding to the side of the same color primary filter used in recording the anaglyph. The other side, corresponding to the side recorded using color filter of the remaining primary colors, has only a fixed or adjustable neutral density filter that matches the luminosity to that of the one primary color filter. Retinal rivalry suppresses the one primary color image on the side of the less luminous neutral density filter image, thus generating full stereopis. Since the side with the neutral density filter perceives all of the primary colors, the color gamut is maintained.

Abstract: The present invention discloses an LCD device and viewing eyewear for obtaining stereoscopic images with conventional single optic channel endoscope using a single lens camera. LCD device comprises two segments each of which is activated by a controller through a wired or wireless connection and is installed between the endoscope and camera without affecting the optic path length. Images are viewed on a standard monitor using eyewear comprising LCD shutters on the left and the right side which are synchronized to the segments in the LCD device by a controller. The LCD shutters on the eyewear are in the upper inner field of vision of each eye. This allows the user, usually a surgeon, to have stereoscopic view when looking at the monitor, but clear view when he has to look at the operative field. The disclosed eyewear has a sterile attachment that the surgeon can use for mounting, un-mounting or adjusting the eyewear.

Abstract: A shaft for endoscope for two handed micro neurosurgery of the brain comprising a Rigid surgical suction at 6 o?clock position that is longer than the shaft, Channel for endoscope at 12 o?clock position, Channel for irrigation, Surgical suction control hole on the shaft, a hand rest on the shaft and a detachable retractor blade.

Abstract: The present invention discloses a device for obtaining stereoscopic images with conventional single optic channel endoscope using a single lens camera. The device comprises of an aperture each half of which is covered with complimentary additive and subtractive color filters and is installed between the endoscope and camera. The filters can be transversely adjusted to center on the principal ray so as to obtain optimal stereopsis. Images are viewed on a standard monitor using eyewear comprising the same complimentary additive and subtractive color filters on the left and the right side, or on specialized video monitors using active or passive polarized glasses.

Abstract: A method and system are provided for retaining user-inputted text values. The method includes, responsive to a user command to compose an email in an email client, opening a compose window including a first text input field, wherein the compose window includes a programmer-defined behavior for the first text input field to save a first text input field value. The method includes receiving a user input in the first text input field. The method includes, responsive to detecting the programmer-defined behavior, saving the user input from the first text input field into an accessible memory.

Abstract: A handy device for retrieving a vehicle stuck in a snow bank with a metal shoe about the width of a tire and roughly conforming the radial curvature of the tire, multiple conical sharp or blunt projections on the under surface of the metal shoe that increase traction on snow or ice, a side plate attached to one side of the shoe at one end and with a hole at the other end, and, a right angled bar, one side of which has multiple small holes and passes through the hole in the side plate and other side of which passes through the existing gaps in the wheel rim, and, a metal pin that locks the angled bar into the hole in the side plate. A preferred embodiment includes wherein the side plate and the angled bar are laminated with plastic or such poor conductor of cold. An alternative embodiment includes wherein the side plate is hinged to the metal shoe on one side with or without the other side fixed through a hinge to the rim of the wheel.

Abstract: A surgically implantable shunt system 20 is provided for controlling fluid flow from a relatively high pressure region to a low pressure region. The system 20 includes a rigid housing 22 defining a sealed chamber 24 therewithin, the housing 22 having an inlet port 26 in fluid communication with the high pressure region, and an outlet port 28 in fluid communication with the low pressure region. A conduit 44 extends through the housing 22 from the inlet port 26 to the outlet port 28 and includes a valve 46 disposed within the sealed chamber 24. The valve 46 regulates fluid flow from the high pressure region to the low pressure region, wherein operation of the valve 46 is dependent upon a pressure P.sub.c external to the conduit 44 and within the sealed chamber 24, and is not susceptible to changes in pressure outside the housing 22.
