Title: Method and system for digital image signatures
Inventor: POWELL ROBERT D
IPC: G06T9/00
Filed: 1993-07-30
Abstract: A method and system for embedding signatures within visual images in both digital representation and print or film. A signature is inseparably embedded within the visible image, the signature persisting through image transforms that include resizing as well as conversion to print or film and back to digital form. Signature points are selected from among the pixels of an original image. The pixel values of the signature points and surrounding pixels are adjusted by an amount detectable by a digital scanner. The adjusted signature points form a digital signature which is stored for future identification of subject images derived from the image. In one embodiment, a signature is embedded within an image by locating relative extrema in the continuous space of pixel values and selecting the signature points from among the extrema. Preferably, the signature is redundantly embedded in the image such that any of the redundant representations can be used to identify the signature. Identification of a subject image includes ensuring that the subject image is normalized with respect to the original image or the signed image.  Preferably, the normalized subject image is compared with the stored digital signature.

Patent CA-2118818-A1 (CA)
Inventor: LIN DAVID S
IPC: G01R31/36
Filed: 1994-03-11
Abstract: A battery pack for a computer system including static memory to maintain battery operating parameters and charge information, a real time clock (RTC) for measuring periods of non-use of the battery and a communication means to exchange the battery information with a microcontroller located in the computer system. The static memory, RTC and communication means is preferably in the form of a single RAM/RTC chip.  The battery pack also includes circuitry to maintain power to the RAM/RTC from the battery if AC power is not available.  The microcontroller detects the presence of the battery and retrieves the present time from the RTC, a timestamp indicating time or removal of the battery and other operating parameters and charge information from the battery pack, and controls the charging functions of the battery accordingly.  The microcontroller also updates the charge information of the battery pack while performing other housekeeping functions of a DC-DC converter.  The microcontroller further controls a switch located in the charge path of the battery to control fast charging.  Trickle charge is simulated by pulsing the switch at a predetermined duty cycle and period.  The microcontroller may be placed in standby to conserve energy, while also monitoring the standby switch to pull the computer system out of standby mode if the standby switch is pressed.  This allows the keyboard controller 21 to be shut off during standby mode to conserve energy.

Abstract: A photo-reactive nail polish coating composition is provided herein that cures quickly upon exposure to low levels of ultraviolet radiation. The coating includes nitrocellulose, a particularly-specified photo-reactive monomer, a particularly-specified photoinitiator and a reaction inhibitor, all in particularly-specified amounts, resulting in a product which is compatible with commercially-available nail polish of any colour, and which is removable by standard acetone-based polish removers. It is also compatible with every-day chores because it is insoluble in water. The composition is not phototoxic and has very low potential for skin irritation or sensitization. The photo-reactive coating is applied over the wet nail polish, and then is irradiated with safe dosages of ultraviolet radiation, causing the nail polish to dry in a few minutes.
