  • Publication number: 20130029427
    Abstract: A real-time, on-line method and analytical system for determining halohydrocarbons in water which operate by (1) extracting on-line samples; (2) purging volatile halohydrocarbons from the water (e.g., with air or nitrogen); (3) carrying the purge gas containing the analytes of interest over a porous surface where the analytes are adsorbed; (4) recovering the analytes from the porous surface with heat (thermal desorption) or solvent (solvent elution) to drive the analytes into an organic chemical mixture; (5) generating an optical change (e.g., color change) in dependence upon a reaction involving the analytes and a pyridine derivative; and (6) measuring optical characteristics associated with the reaction to quantify the volatile halogenated hydrocarbon concentration.

  • Patent number: 8277414
    Abstract: An injection device (210; 110) is described. A housing (212; 112) receives a syringe and includes a return spring (226; 126) for biasing the syringe from an extended position in which its needle (218; 118) extends from the housing (212; 112) to a retracted position in which the it does not. A drive spring (230; 130) acts on a first drive element (232; 132) and a second drive element (234; 134) acts upon the syringe to advance it from its retracted position to its extended position and discharge its contents through the needle. The first drive element (232; 132) is capable of movement relative to the second (234; 134) once a nominal decoupling position has been reached. A release mechanism is activated when the first drive element (234; 134) is further advanced to a nominal release position, to release the syringe (214; 114) from the action of the drive spring (230; 130), whereupon the return spring (226; 126) restores the syringe (214; 114) to its retracted position.

  • Patent number: 8156318
    Abstract: A device management system for securely storing an encryption key associated with a device management session. The device management system includes an encryption key generator to generate an encryption key, a client device to receive an encrypted bootstrap data file transmitted by a base station, and a network interface controller coupled to the client device, the network interface controller to store the encryption key separate from a system memory of the client device. Embodiments of the device management system ensure user credentials do not exist in the client device in plaintext form outside of the network interface controller, thus preventing software and/or malware executed on the host from extracting such credentials.

  • Patent number: 8095794
    Abstract: A system and method of generating a watermarked signal are disclosed. The system segments the signal into overlapping blocks using a window function and processes the overlapping blocks according to whether each block is odd- or even-numbered. The system windows the odd-numbered blocks, modulates the phase of each block in the frequency domain, transforms each modulated block in the time domain, windows each block transformed into the time domain and overlap-adds each odd-numbered block with each even-numbered block to generate the watermarked signal.

  • Patent number: 8086670
    Abstract: The present invention relates to a system and methodology facilitating network communications between an industrial control system and a client application that interacts with a plurality of data items on the control system. The client application initiates a request or query to the industrial control system for an identification of selected data items of interest. Based on information received in the request, an aggregation component can be constructed by the client, wherein names and buffer allocations relating to the data items of interest are provided. The aggregation component is then installed by the client and updated in the industrial control system, thus providing information access to the client application when fresh or updated information is desired. Information is accessed via a communications packet that is generated from the data items identified in the aggregation component.

  • Publication number: 20110283070
    Abstract: The subject matter disclosed herein describes a method of allocating and persisting memory in an industrial controller without requiring a battery backup or a large capacitive storage system. Each data object is identified as static or dynamic. Static objects are further classified by whether frequent access of that data object is required. Each of the data objects is stored in non-volatile memory. The dynamic data objects and static data objects requiring frequent access are stored in volatile memory. A record of static data objects is maintained in non-volatile memory and a record of dynamic data objects is maintained in volatile memory. Upon power loss, the present value of each dynamic data object is copied to non-volatile memory. When power is restored, the values of both the dynamic data objects and the static data objects that require frequent access at run-time are copied from non-volatile memory to volatile memory.

  • Publication number: 20110226253
    Abstract: A cough shield includes a cough shield body expandable from a folded state to an open state and collapsible to return from the open to the folded state. The cough shield body is retained in an unbiased condition in the folded state until acted on by a user to open the cough shield body. An engagement member adhesively fixed to the body is accessible to the user in the folded state. The engagement member defines a cavity between the engagement member outer wall and an outer surface portion of the body. The engagement member slidably receives a user's finger to assist in opening or closing the cough shield body and to temporarily retain the cough shield in the open state in contact with the face of the user to at least partially cover the user's nose and mouth.

  • Publication number: 20110178469
    Abstract: The present invention concerns an injection device with a housing adapted to receive a syringe having a discharge nozzle, the housing having an indicator opening. There is a trigger and a forward drive arranged to act upon the syringe on actuation of the trigger to advance the syringe from a retracted position to an extended position thereby discharging the contents of the syringe through the discharge nozzle. A support member is in contacting juxtaposition with the housing and a return drive is supported by the support member and arranged to act upon the syringe after the contents of the syringe has been discharged so that the syringe can be withdrawn from the extended position to the retracted position. Advantageously, the support member is arranged in the housing so that the second drive does not obscure an inspection of the contents of the syringe through the indicator opening. Hence, it can be clearly determined whether the contents of the syringe have been expelled from the syringe.
