Abstract: Enhanced Bluetooth and/or cellular frequency hopping radios are integrated into a hands-free wireless mobile computing and video display headset. Forms of these enhanced headsets incorporating the enhanced frequency hopping spread spectrum radio technology are of interest to military, police, fire fighters, first responders and certain commercial companies such as utility companies seeking private cellular systems seeking enhanced communication privacy.

Abstract: A head mounted display (HMD) system includes a number of separately and uniquely packaged components. A first component is a headset that incorporates at least a microphone input and speaker output devices into headset housing apparatus designed to be supported about the user's head or face. A microdisplay element is located in an optical pod at the end of an adjustable boom as part of the headset. Additional components, including electronic circuits, such as a microcomputer, one or more wired and wireless interfaces, associated memory or storage devices, auxiliary device mounts and the like are packaged in the headset or as a pager sized gateway device having a belt clip.

Abstract: Connections, software programming and interaction between a smart phone and a Head Mounted Display (HMD) or other video eyewear to improve user experience. The signal from an accelerometer and/or a touch screen in a smart phone is used only for certain control of an application program, such as to steer a racing car or a plane or to move a game persona character within a virtual space. The main scene for the game is displayed in the HMD and not the smart phone screen. One or more inputs from the HMD such as a head tracker or camera, are connected to the smart phone either via a wire or wirelessly such as via WiFi or Bluetooth. The head tracking and/or camera inputs are used as another input to the game, such as to pan/zoom or change the viewpoint of the user. In a still further implementation, the HMD also can have an integrated processor to make it a “smart” HMD.

Abstract: A handheld wireless display device, having at least SVGA-type resolution, includes a wireless interface, such as BluetoothrM, WiFi™, Wimax™, cellular or satellite, to allow the device to utilize a number of different hosts, such as a cell phone, personal computer, media player. The display may be monocular or binocular. Input mechanisms, such as switches, scroll wheels, touch pads, allow selection and navigation of menus, playing media files, setting volume and screen brightnesdcontrast, activating host remote controls or performing other commands. The device may include MIM diodes, Hall effect sensors, or other position transducers and/or accelerometers to detect lateral movements along and rotational gestures around the X, Y and Z axes as gesture inputs and movement queues. These commands may change pages, scroll up, down or across an enlarged screen image, such as for web browsing. An embedded software driver permits replicating a high-resolution screen display from a host PC.

Abstract: A remote control microdisplay device that uses hand and head movement and voice commands to control the parameters of a field of view for the microdisplay within a larger virtual display area associated with a host application.

Abstract: A wireless headset can incorporate a wireless communication controller that not only provides a video link to a host device, but also provides for control and management of a host device and other more devices. In this context, a host device may be any appropriate device that sources audio, video, text, and other information, such as a cell phone, personal computer, laptop, media player, and/or the like.

Abstract: An apparatus includes a monocular display with a wireless communications interface, a user input device, a transmitter, and a controller. The monocular display is positioned relative to the user's eye to display images to the user while occluding less than half of the user's maximum viewing space. The apparatus can incorporate a wireless communication controller that not only provides a video link to a host device, but also provides for control and management of a host device and other more devices. In this context, a host device may be any appropriate device that sources audio, video, text, office functionality and other information, such as a cell phone, personal computer, laptop, media player, and/or the like. The apparatus and the host may support Microsoft Windows SideShow, Remote Desktop Protocol (RDP), and Virtual Network Computing (VNC).

Abstract: A method for providing information to a customer who is requesting a synthesized oligonucleotide, peptide, peptide nucleic acid, polysaccharide or antibody (collectively “strands”). The capabilities of one or more suppliers are stored and automatically searched for capabilities to synthesize the requested strand. A list of the suppliers with the required capabilities is generated along with the price of the strand. The invention also encompasses an apparatus for providing information to remote users regarding which suppliers can supply a desired strand. The apparatus has a database and a server which allows the remote user to access the capabilities of one or more suppliers for synthesizing a strand.

Abstract: A process is described for the preparation of a compound of formula (I) or a stereoisomeric compound thereof, in which the 1,2-position is saturated or is a double bond; X.sup.1 and X.sup.2 are each independently hydrogen or halogen; R.sup.1 is hydrogen or acyl; R.sup.2 is hydroxyl, acyloxy or oxo; and R.sup.3 is alkyl, by reacting a compound of formula (II) with an aldehyde R.sup.3 CHO in either phosphoric acid or about 60% to about 75% w/w sulphuric acid. Compounds of formula (I) are either pharmacologically active steroids or are intermediates in the synthesis of pharmacologically active steroids.

Abstract: This invention provides a method of concentrating a metaliferous ore containing also substantial quantities of pyrites and/or pyrrhotite and/or sphalerite and comprises subjecting an aqueous pulp of the ore to a froth flotation process in the presence of a depressant and in which (1) pyrites and/or pyrrhotite, and/or (2) sphalerite, is depressed by using as the depressant an amine in which at least 20% of the total number of amine groups are tertiary amine groups and in which the number of quaternary amine groups present is zero or is less than one-third the number of tertiary amine groups.

Abstract: A method of concentrating a metalliferous ore containing also substantial quantities of pyrites and/or pyrrhotite and/or sphalerite and comprises subjecting an aqueous pulp of the ore to a froth flotation process in the presence of a depressant and in which (1) pyrites and/or pyrrhotite, and/or (2) sphalerite, is depressed by using as the depressant a condensation product of an aldehyde with a compound containing at least two amine or amide groups.
