Abstract:
An optical receiver and a method of demodulating an optical signal. The method includes combining a received optical signal with a local oscillator signal to construct a complex signal indicative of an optical field of the modulated optical signal and processing the complex signal recursively under control of a Kalman filter that enforces a constraint. The receiver includes an optical hybrid that combines a received optical signal with a local oscillator signal, a detector that recovers components of a complex signal, a processor that receives these components, and instructions that cause the processor to process the components of the complex signal recursively under control of a Kalman filter that enforces a constraint to recover data.
Abstract:
The present invention relates to arrangement of devices, and, in particular doors, in the architecture of HVAC units. Where space is a consideration, having doors that are common and/or that can be used or nestled in a common operative space, reduce the need of inventory of different parts, and allow for use of smaller interior HVAC space volumes in HVAC units.
Abstract:
The present invention relates to air distribution for vehicle heating, ventilation and air conditioning systems having a preferably semi-lateral HVAC architecture configuration. The semi-lateral HVAC system provides for a bend or turn in the housing between the evaporator and heating means of the HVAC unit wherein a rotational device with moveable vanes is located, to provide improved air flow temperature and flow control over traditional lateral HVAC architectures, while employing less space and a lower piece count.
Abstract:
A logical device that is coupled to a computer can be controlled using string commands. The logical device requires flags and a data structure to operate properly. A string command with tokens for operating a specific logical device is provided. A linked list of the tokens is created. A command table for the specified logical device is found. The command table contains possible commands for the logical device, which commands are able to provide the required flags and data structure for the logical device. Each command in the command table contains key words or tokens or multiword tokens. The command table tokens are parsed, one at a time, against the command string tokens. If no match between the command table token and a command string token occurs, then the next command table token is parsed against the command string tokens. If a match between a command table token and a command string token occurs, then the flag that is associated with the command string token is provided and data from either the command string token or the command table token is inserted into the data structure in its proper place.
Abstract:
Disclosed are systems and methods for recording, maintaining, and reporting tips and gratuities, optionally including details such as employee, task performed, and shift. In one aspect, inter-employee tip and gratuity transactions are tracked and verified. In another aspect, taxing authority forms and/or returns are automatically generated with substantially decreased administration time and cost, thereby facilitating a user's participation in voluntary taxing authority programs. Additionally, the training required by such programs is automatically monitored. In yet another aspect, tips and/or gratuities may be paid as wages. In another aspect of the present invention, employees are provided an opportunity to increase declared tips if the originally declared tips place employee in jeopardy of an audit. In another aspect, interfaces to third-party systems such as POS systems, payroll systems, and the like are provided to further minimize system administration time and data accuracy. In another aspect, Web-based systems are provided.
Abstract:
High speed networking systems such as PCI-Express and Serial Rapid I/O are based on the exchange of packets across switched networks of high speed serial links. Information in the headers of these packets indicate the kind of transaction they represent. Queuing all received packets in a single queue will cause interactions between transaction types. Indirection can be used create the effect of multiple independent queues from a shared memory. This provides efficient centralized packet storage, while allowing independent processing of different transactions types.
Abstract:
The Rapid I/O Messaging Logical Layer relies on the receiving device to map the incoming messages into specific memory locations. This uses software programmable mapping registers. The settings are compared to the header fields of the incoming Rapid I/O messages to determine if there is a match, in which case, the packet is mapped to a queue. Accessibility to a queue through the mapping register can be limited to discrete MAILBOX/LETTER combinations, or multiple combinations based on the masking bits. Long messages may be processed through a hardware lookup table implemented to break up transactions into Rapid I/O compliant packets.
Abstract:
The present invention relates to the field of directing ventilating air and airflow control in a ventilating, heating or air conditioning system. More specifically, the present invention relates to a structure and method to provide air flow mixture via with reduced heat pickup utilizing a separate piece air deflector located within the lower housing of the HVAC unit, and ribs to direct airflow. The HVAC unit provides an inserted deflector means which provides for smaller packaging volume, allows air deflection and airflow towards the distribution area of the unit, and, provides a drainage means for undesired water, before it reaches the distribution area, yielding an HVAC unit, with the same functionality as larger HVAC units.
Abstract:
An apparatus for mixing material in a container includes a platform mounted for simultaneous movement on at least two axes and for supporting a container containing material to be mixed. A motor can be operatively associated with the platform to move the platform on the two axes. A container holding assembly having a vertical extent can be carried by the platform, and is moveable between a closed position in which the holding assembly is positioned proximate the container to retain the container on the platform during mixing operations, and an open position in which the holding assembly is positioned away from the container so that the container can be removed from the platform without lifting the container over the vertical extent of the holding assembly. The platform can be contained within a housing having a low profile opening such that the container can be removed without elevating the container.
Abstract:
A virtual reality generator having an input module that receives as input financial information is disclosed. The virtual reality generator outputs to a display device a virtual reality world generated from the financial information. The financial information can be preprocessed by a financial analytic system prior to input to the virtual reality generator. The financial information can be received from a data file. The virtual reality generator can dynamically display and continuously update the virtual reality world. Further, movement through the virtual reality world can be simulated.
