A method of forming a minute resist pattern wherein a positive-working photoresist composition containing 3 to 15 parts by weight of a quinone diazide group-containing photosensitizer relative to 100 parts by weight of alkali-soluble novolak resin is developed by an aqueous organic or inorganic alkali solution having a lower alkali concentration than that of the conventional one as the developer. The preferable example of the organic alkali materials in the developer is quaternary ammonium hydroxide, and the preferable example of the inorganic alkali materials in the developer is alkali metal hydroxide. The concentrations of the quaternary ammonium hydroxide and the alkali metal hydroxide in the developing solution are 2.2% by weight or less and 0.4% by weight or less respectively. Using such developing solution, high sensitivity, a high film retention rate, high resolution, low process dependency of dimension accuracy, and a formation of excellent pattern profile can be achieved.

Known methods of producing large-surface integrated thin-film solar modules with an amorphous, poly- or microcrystalline absorber layer always comprise division and conversion structuring processes which can cause instabilities in the structuring and which are relatively expensive. According to the inventive method which can be used to fabricate substrate solar cells and superstrate solar cells, the mask which is used provides for structuring itself during the deposition of layers for the rear electrode and the absorber layer through its geometrical form. The use of a mask which can be reused as an independent element after use in this method allows for a relatively free range of possible geometric forms. This also makes possible applications inside and outside of buildings, including in the area of a window, from an esthetic and informal point of view. These types of application are also supported by the possibility of a structural connection between the solar modules produced according to the inventive method and light-collecting concentrator modules, in order considerably to increase their average and total energy conversion efficiency.

A method and system of lossless compression of integer data using a novel backward-adaptive technique. The adaptive Run-Length and Golomb/Rice (RLGR) encoder and decoder (codec) and method switches between a Golomb/Rice (G/R) encoder mode only and using the G/R encoder combined with a Run-Length encoder. The backward-adaptive technique includes novel adaptation rules that adjust the encoder parameters after each encoded symbol. An encoder mode parameter and a G/R parameter are adapted. The encoding mode parameter controls whether the adaptive RLGR encoder and method uses Run-Length encoding and, if so, it is used. The G/R parameter is used in both modes to encode every input value (in the G/R only mode) or to encode the number or value after an incomplete run of zeros (in the RLGR mode). The adaptive RLGR codec and method also includes a decoder that can be precisely implemented based on the inverse of the encoder rules.

Deinterleaving is performed using a “smart” direct memory access (DMA) function. The deinterleaver, which may be a modified DMA controller, can be programmed with a step size so that the deinterleaver reads every Nth byte from the memory. The deinterleaver automatically increments the source memory address by the step size to read successive bytes of a codeword. The deinterleaved data can be written to the same memory, to a different memory, or to some other device.

A method for distribute or share data provided by a server process of an industrial control system to a client process running on a first machine of a first user, with a client process running on a machine of a second user. The server session is logged by the server process. It is determined that the first user makes a selection to distribute or share a client process with at least one second user. An address is retrieved for the at least one other user, and a channel is opened thus providing the same data provided to the client process running on the first machine to a client process running on a second machine of at least one second user. Also system, a human-machine interface and a computer program for carrying out the method.

Acoustic perfusion devices for separating biological cells from other material in a fluid mixture are disclosed. The devices include an inlet port, an outlet port, and a collection port that are connected to an acoustic chamber. An ultrasonic transducer creates an acoustic standing wave in the acoustic chamber that permits a continuous flow of fluid to be recovered through the collection port while keeping the biological cells within the acoustic chamber to be returned to the bioreactor from which the fluid mixture is being drawn.

An apparatus and a method for dynamically determining a connection establishment mechanism between virtual machines (VMs) based on locations of the VMs. The apparatus includes a communication agent unit for receiving messages relating to the locations of the VMs, a control unit for determining the connection establishment mechanism between the VMs based on the received messages and a controlling mechanism to establish a connection between the VMs according to the determined connection establishment mechanism. The method includes receiving messages relating to the locations of the VMs, determining the connection establishment mechanism between the VMs based on the received messages, and establishing a connection between the VMs according to the determined connection establishment mechanism.

A computer may identify an individual according to one or more biometrics based on various physiological aspects of the individual, such as metrics of various features of the face, gait, fingerprint, or voice of the individual. However, biometrics are often computationally intensive to compute, inaccurate, and unable to scale to identify an individual among a large set of known individuals. Therefore, the biometric identification of an individual may be supplemented by identifying one or more devices associated with the individual (e.g., a mobile phone, a vehicle driven by the individual, or an implanted medical device). When an individual is registered for identification, various device identifiers of devices associated with the individual may be stored along with the biometrics of the individual. Individuals may then be identified using both biometrics and detected device identifiers, thereby improving the efficiency, speed, accuracy, and scalability of the identification.

Methods are disclosed for separating beads and cells from a host fluid. The method includes flowing a mixture containing the host fluid, the beads, and the cells through an acoustophoretic device having an ultrasonic transducer including a piezoelectric material driven by a drive signal to create a multi-dimensional acoustic standing wave.

A recirculating fluid stream having a tangential flow path is located substantially tangential to the standing wave and separated therefrom by an interface region. A portion of the cells pass through the standing wave, and the beads are held back from the standing wave in the recirculating fluid stream at the interface region. Also disclosed is an acoustophoretic device having a coolant inlet adapted to permit the ingress of a cooling fluid into the device for cooling the transducer.
