Project a laser beam onto an object inside a garage directly or through a reflector so that the projection is visible to a vehicle driver.

Abstract: Functionality is described for compressing and decompressing mass spectrometry data, therefore making it easier to store, retrieve, transfer, and process the mass spectrometry data. The functionality operates by mapping data values (e.g., mass-to-charge data values or intensity data values) into index values, and then mapping the index values into delta values. The functionality then uses an encoding algorithm (such as a coding tree) to represent the delta values in compressed form. In a decoding stage, the functionality can interpret each encoded delta value with reference to a chain of preceding delta values, which ultimately link to an initial data value that is expressed in non-relative form. In one implementation, the functionality can define multiple such initial data values which correspond to multiple access points in a stream of compressed mass spectrometry data.

Abstract: Arithmetic coding utilises probability values associated with contexts and context indexed values. The probability values are stored within a random access memory 6 from where they are fetched to a cache memory 8 before being supplied to an arithmetic encoder and decoder 4. The context indexed values used are mapped to the plurality of contexts employed such that context indexed values used to process data values close by in a position within the stream of data values being processed have a greater statistical likelihood of sharing a group of contexts than context values used to process data values far away in position within the stream of data values. Thus, a group of contexts for which the probability values are fetched together into the cache memory 8 will have an increased statistical likelihood of being used together in close proximity in processing the stream of data values. This reduces the number of cache flush operations and cache line fill operations.
