Abstract: Described is a thermogravimetric analyzer system. The system includes an evaporator having first and second fluidic channels and a thermally controlled heater assembly. The first fluidic channel has a first channel inlet in fluidic communication with a gas supply module, a first channel outlet and an end portion extending from the first channel outlet. The second fluidic channel has a second channel inlet in fluidic communication with a source of liquid and a second channel outlet disposed on the first fluidic channel at a merge location between the first channel inlet and the first channel outlet. The end portion of the first fluidic channel includes a bend to redirect a flow within the first fluidic channel and improve a mixing of the gas and liquid received by the first and second fluidic channels, respectively.

Abstract: A computer includes at least one processor and at least one computer readable storage medium accessible to the processor. The medium bears instructions executable by the processor to cause the processor to receive at least one image of at least one viewer of a display on which content is presented. The instructions also cause the processor to generate a signal representative of at least one expression of the viewer made at or around the time the content was presented based on the image of the viewer, and also to receive metadata identifying the content. The instructions then cause the processor to associate the metadata identifying the content with the at least one expression of the viewer.

Abstract: A user can define a gesture-based input mode with respective input value to establish an authentication protocol to unlock a computer or govern other computer behavior. As an alternative or in addition, the user can define a second input mode based on face recognition plus IR sensing satisfying a threshold to ensure a live person is being imaged for authentication, and/or face recognition plus a particular facial expression such as a smile and wink.

Abstract: According to one embodiment of the invention, a method for setting permission levels is described. First, an application and digital signature is received by logic performing the permission assessment. Then, a determination is made as to what permission level for accessing resources is available to the application based on the particulars of the digital signature. Herein, the digital signature being signed with a private key corresponding to a first public key identifies that the application is assigned a first level of permissions, while the digital signature being signed with a private key corresponding to a second public key identifies the application is assigned a second level of permissions having greater access to the resources of an electronic device than provided by the first level of permissions.

Abstract: An apparatus and method are provided for a client application to provide a video stream as well as data regarding the video stream to an output device, where the data is generated from a process performed at a layer lower than the client application layer. By this, multiple client applications can simultaneously utilize the data generated by the lower-level process while at least one client application can effect streaming of the video stream to an output device.

Abstract: An endoscope for quantitatively determining dimensions of an object in a cavity is provided. The endoscope has a projector connected to a light guide that can be introduced through the instrument channel. In the introduced position the projector projects a pattern at a defined illumination angle onto the object to be examined. The endoscope has a camera that captures the projected pattern at a fixed viewing angle in a distorted from corresponding to the object. The distorted form is used for quantitatively determining dimensions of the object by a triangulation method.

Abstract: A method and apparatus is provided for arbitrating client application access to at least one resource by determining two or more client applications of a plurality of client applications to grant simultaneous access to the at least one resource. By this, data and resources are exposed to multiple client applications and simultaneous multiple use of resources by separate multiple client applications can be achieved.

Abstract: Shock absorber having variable damping characteristics. The shock absorber includes a shock absorber cylinder containing a damping medium. A piston rod extends into the shock absorber cylinder. A piston is arranged on a free end of the piston rod. The piston is structured and arranged to divide a space inside the shock absorber cylinder into two chambers. The two chambers are in fluid communication with each other via a main flow channel and a plurality of secondary flow channels. A valve device is structured and arranged to open and close the secondary flow channels. The valve device comprises a plurality of separately controllable spool valves movably arranged on a base member and a plurality of valve members having different flow characteristics. One of the valve members is assigned to one of the secondary flow channels and another of the valve members is assigned to another of the secondary flow channels.

Abstract: A shock absorber wherein the piston of the piston-piston rod assembly divides the internal space of the cylinder into first and second chambers. The piston has first and second passages for the flow of fluid between the chambers in response to shifting the assembly relative to the cylinder and/or vice versa. One of these passages is controlled by a first check valve which prevents the flow of fluid through the one passage from the first chamber into the second chamber. A second check valve prevents the flow of fluid through the other passage from the second chamber into the first chamber. The piston-piston rod assembly further defines a plurality of bypasses each of which is controlled by a solenoid valve as well as by a pressure-responsive valve.

Abstract: A shock absorber with a variable damping characteristic has a piston which is reciprocable in a cylinder to divide the oil-filled internal space of the cylinder into two chambers. The chambers are connectable to each other by one or more passages so that oil can flow between the chambers in response to movement of the piston relative to the cylinder and/or vice versa. The piston has several bypasses each of which is controlled by an adjustable electrically operated regulating valve. In order to enhance the accuracy of regulation of flow of oil between the chambers by way of the bypasses, the piston is formed with channels which supply oil between the mobile valving elements and the seats of the valves to thus reduce or eliminate friction between such parts.

Abstract: A nuclear magnetic resonance tomography apparatus, and a method for operating such an apparatus, generate a tomographic image by projecting acquired signals corresponding to the nuclear spins on a frequency axis as a Fourier line, and the image of the examined slice is calculated by Fourier transformation of the Fourier lines. In the method and apparatus, a number of echo sequences are acquired after excitation of the nuclear spins in the axamination subject by a high frequency pulse. Each echo sequence consists of a selected number of individual echoes occurring in succession within each sequence. In the method and apparatus, entry of these individual echoes into a matrix having a central zero line is controlled such that the first-occuring echoes from each sequence are entered in the matrix on alternating sides of the zero line, i.e., above and below the zero line, at increasing distances from the zero line.

Abstract: A staff-location and signal system for mines, in which conventional radio telephone devices can be used for producing a radio telephone connection between an exchange and base stations or between the base stations and radio telephone equipment in the mine area. All underground employees, whether they carry radio telephones or not, can be reached by warning signals or staff-location signals sent via apparatus carried by the employees. To this end, the miner's lamps are associated with radio receivers which respond to cooled signals transmitted by the base station and thereupon actuate a switching device. The normally-closed working-current circuit of the lamp contains a switch which can be operated by the actuated switching device so that it switches the miner's lamp on and off. In this manner all miners can be raised when necessary by warning or staff-location signals in the form of flashes.

Self-adhering or heat-sealable papers produced by these methods.
