Title: Language learning system and a digital storage unit
Inventor: NIEMINEN EERO
IPC: G10L19/00
Filed: 2002-05-31
Granted: 2010-11-23
Abstract: Audio recordings and programs are saved as audio files on a digital storage unit in a language learning system comprising student units connected to the digital storage unit. The digital storage unit is provided with a audio interface controller (201) having a dedicated input/output RAM buffer (B1-B63) for each student station. Each RAM buffer has an associated file which is either a fixed file or can be defined for each case. When the audio interface controller (201) receives a record command relating to a specific buffer, the controller (201) opens an audio file associated with the specific buffer, buffers the audio data received from a student station or another source in the buffer, and transfers the contents of the specified buffer to the opened associated audio file. Similarly, in response to a play command relating to a specific RAM buffer, the controller (201) opens an associated audio file in the digital storage unit, transfers audio data from the opened audio file to the buffer, and sends the audio data from the buffer to a respective student station or to other destination.

Abstract: A method for viewing a first object that is obstructed by a second object. In such a method, the first object has a contrasting color to the second object and the second object is constructed from a material that allows visible light to pass therethrough. The amount of visible light that passes through the second object is not enough such that the first object is visible to the human eye. The method involves taking a digital image of the first and second object using a visible light sensor, such as a CCD camera sensor. The digital image data that is received into a computer system contains both first object data and second object data. It should be understood that the first object data and the second object data include color information. The amount of contrast between the first and the second object should be approximately 10% of the total scale such that on a 256 color scale the difference is approximately 25 levels. The computer system substantially filters out the second object data and then the values associated with the first object data are increased until the data is visibly displayable.

Abstract: A key distribution server maintains a tree of nodes. Members of a group who are allowed access to information are associated with respective leaf nodes of the tree. The information is encrypted with a key comprising a join key field and a leave field, and these are associated with the root node of the tree. The join key is updated each time a member joins the group and the leave field is updated each time a member leaves. Further respective leave keys are associated with the other nodes of the tree. The leave keys of the tree are related so that a member knowing the leave key of its node can work out the leave key of the root node and hence decrypt the information. The key distribution server transmits offset messages to the members to allow them so to calculate the root node leave key. The system of offset messages reduces the amount of communication required between the key distribution server and the group members.

Title: Clock and data recovery phase-locked loop and high-speed phase detector architecture
Inventor: BRUNN BRIAN T
IPC: H03D3/24
Filed: 2004-01-16
Granted: 2012-05-15
Abstract: A clock recovery circuit and a high speed phase detector circuit that operate at a clock speed equal to one-half the input data rate (i.e., a half-rate clock) are presented. The clock recovery circuit uses dual input latches to sample the incoming serial data an both the rising edge and falling edge of a half-rate clock signal to provide equivalent full data rate clock recovery.  The clock recovery circuit functions to maintain the half-rate clock transitions in the center of the incoming serial data bits. The clock recovery circuit includes a phase detector, charge pump, controlled oscillation module and a feedback module. The phase detector produces information on the phase and data transitions in the incoming data signal to the charge pump.  Generally, the circuit is delay insensitive and receives phase and transition information staggered relative to each other. The high speed phase detector circuit provides phase information and transition information from incoming serial data. The high speed phase detector circuit samples the incoming serial data on both the rising edge and falling edge of the half-rate clock to provide equivalent full high speed data rate sampling. The high speed phase detector circuit generates a delay between the phase information and the transition information. The phase information is produced in a first bit period and the transition information is produced in a second bit period relative to the first bit period.
