Title: Unique identifier for biological samples
Inventor: WILLIAMSON JANICE M
IPC: G16B50/20
Filed: 1999-02-25
Abstract: The present invention provides a method for internal labelling of a biological sample by which the sample is identifiably linked to its source and other relevant information, based on the polymorphisms inherent in the sample itself. A set of polymorphisms in the sample is detected, and the resulting data is used as a unique identifier which is then used to identify the sample. This unique identifier can also be used to identify the source of the sample, and any other relevant information.
Patent CA-2322623-A1 (CA)
Inventor: YANAGIMACHI RYUZO
IPC: C12N5/075
Filed: 1999-03-18
Abstract: The invention provides a method for freeze-drying spermatozoa to obtain at least one reconstituted spermatozoon whose head (nucleus) is capable of fertilizing an oocyte to produce a live offspring. The motility of spermatozoa which have been freeze-dried and stored in a vacuum at room temperature is not restored when rehydrated. Their plasma membranes are disrupted and they are all "dead" in the conventional sense. However, when they are injected microsurgically into oocytes, their nuclei transform into male pronuclei and participate in normal embryonic development.

Title: Method for one-way hashing of values using a correlation processor
Inventor: KHANINE DMITRI
IPC: H04L9/28
Filed: 2000-10-16
Abstract: A method of repeatably non-reversibly encrypting data is disclosed. According to the method, one-way encryption, or hashing, is performed using a neural network. A first number is provided to a neural network as an input value for being encrypted. The output value provided by the neural network is an encrypted value. The neural network is modified at intervals in a predictable or easily synchronised fashion to ensure that multiple neural netwroks can each produce similar results with a same set of input values. Modifying the neural network at intervals reduces a risk that someone will decode the transform technique.

Title: Method for differentiating between burdened and cracked ultrasonically tuned blades
Inventor: DONOFRIO WILLIAM T
IPC: A61F9/007
Filed: 2001-10-17
Abstract: A method for differentiating between ultrasonically tuned blades which are broken or cracked, and blades which are gunked by evaluating measured impedance differences when a system is first excited with a low displacement signal and then with a high displacement signal. The method is performed irrespective of the age of the hand piece/blade, the temperature or specific type of hand piece or blade, and is not affected by self healing effects of slightly cracked blades. Moreover, the method facilitates the quantifiable determination of the amount of gunk on the blade. Absolute impedance measurements of the transducer or blade are unnecessary.  Instead, only relative impedance measurements are required, which greatly simplifies the measuring criteria. This provides a way to measure the amount of gunk accumulation, and thereby a way to calculate/estimate the amount of heat generated at the sheath, as well as a way to calculate/estimate the amounts of degradation to the load curve of the ultrasonic system.
