A substrate processing apparatus having a transport apparatus, at least one sensor connected to the transport apparatus and a controller. The transport apparatus is adapted for transporting the substrate between processing stations of the processing apparatus. The sensor is capable of sensing the substrate transported by the transporting apparatus. The sensor is arranged for sending at least one signal in response to sensing the substrate. The controller is communicably connected to the sensor and arranged to determine alignment of the substrate in at least two directions, angled relative to each other, relative to a predetermined location. The controller is capable of determining alignment from the at least one signal identifying no more than two points on the substrate and independent of radial variances between substrates.

A method of substrate eccentricity detection includes includes determining at least three positions on a perimeter of a first substrate, grouping the at least three perimeter positions to define one or more circles, estimating a location of a center of the first substrate as the location of a center of a predetermined circle approximated from the at least three perimeter positions, and determining an eccentricity vector as a difference between the estimated location and a reference position on a substrate transport mechanism on which the first substrate rests.

Systems and methods are disclosed for enabling a recipient of a cryptographically-signed electronic communication to verify the authenticity of the communication on-the-fly using a signed chain of check values, the chain being constructed from the original content of the communication, and each check value in the chain being at least partially dependent on the signed root of the chain and a portion of the communication. Fault tolerance can be provided by including error-check values in the communication that enable a decoding device to maintain the chain's security in the face of communication errors. In one embodiment, systems and methods are provided for enabling secure quasi-random access to a content file by constructing a hierarchy of hash values from the file, the hierarchy deriving its security in a manner similar to that used by the above-described chain. The hierarchy culminates with a signed hash that can be used to verify the integrity of other hash values in the hierarchy, and these other hash values can, in turn, be used to efficiently verify the authenticity of arbitrary portions of the content file.

A consistent tie-breaking decision between equal-cost shortest (lowest cost) paths is achieved by comparing an ordered set of node identifiers for each of a plurality of end-to-end paths. Alternatively, the same results can be achieved, on-the-fly, as a shortest path tree is constructed, by making a selection of an equal-cost path using the node identifiers of the diverging branches of the tree. Both variants allow a consistent selection to be made of equal-cost paths, regardless of where in the network the shortest paths are calculated. This ensures that traffic flow between any two nodes, in both the forward and reverse directions, will always follow the same path through the network.

A Mixed Media Reality (MMR) system and associated techniques are disclosed. The MMR system provides mechanisms for forming a mixed media document that includes media of at least two types (e.g., printed paper as a first medium and digital content and / or web link as a second medium). In one particular embodiment, the MMR system includes an action processor and method, and MMR documents with an associated action. The MMR document structure is particularly advantageous because the ability to specify different actions for different MMR documents, combined with the ability to create any number of MMR documents for a particular location on any media, allows the MMR architecture to serve as a universal trigger or initiator for additional processing. In other words, addition processing or actions can be triggered or initiated based on MMR recognition. The action processor receives the output of the MMR recognition process which yields an MMR document including at least one action. The action processor executes that action which includes various commands to the MMR system or other systems coupled to the MMR system. The MMR system architecture is advantageous because an action can be executed by pointing the capture device at a block of text, and the action is performed. Example actions include retrieving the text in electronic form to the capture device, retrieving the specification for the action, inserting data to a MMR document, transferring data between documents, purchasing items, authoring actions or reviewing historical information about actions. The MMR system includes a variety of user applications (one or more actions) initiated by the MMR recognition of a text patch such as information retrieval for a travel guide book, stock listings or advertisements; information capture such as recording content from a conference, recording and storing multimedia associated with the document, capturing information for a calendar and on the fly authoring; purchasing media files for storage on any part of an MMR document.

A decryption scheme for recover of a decrypted object without a cryptographic key is described. First, logical operation(s) are conducted on data associated with a first data string expected at a first location within an object having the predetermined format and data within the encrypted object at the first location to recover data associated with a portion of a cryptographic key from the encrypted object. Thereafter, logical operation(s) are conducted on that data and a first portion of the encrypted object at a second location to produce a result. Responsive to the result including data associated with the plaintext version of the second data string, logical operation(s) are conducted on a second portion of the encrypted object and the data associated with the plaintext version of the second data string to recover data associated with the cryptographic key. Thereafter, the encrypted object may be decrypted using the cryptographic key.

A load control system for a building having a lighting load, a window, and a heating and cooling system comprises a lighting control device for controlling the amount of power delivered to the lighting load, a motorized window treatment comprising a window treatment fabric for covering the window, a temperature control device for controlling a setpoint temperature of the heating and cooling system to thus control a present temperature in the building, and a dynamic keypad comprising a visual display and operable to receive a user input. The dynamic keypad allows a user to select, adjust, and monitor a plurality of energy-savings modes of the load control system. For example, the dynamic keypad allows the user to enable and adjust a setback temperature of the temperature control device on-the-fly.

A method and system directed to negotiating and triggering media stream synchronization at the link layer in a QoS-enabled 802.11 WLAN, or other wireless, network. In one implementation, the present invention allows for improved performance of streaming network applications, such as video conferencing, over wireless links. In one implementation, the present invention also provides an optional mechanism whereby a mobile station can signal a need for on-the-fly throttling, if an application on the mobile detects that there is a need for better synchronization of two streams, such as a lower priority stream to a higher priority stream.
