Patent number: 8683232Abstract: A portable storage device has a storage peripheral interface connecting to a computer. An encrypted data storage is available to the computer connected to the interface. The encrypted data storage includes a first part accessible after an authentication. A controller has a first operation mode performing encryption and decryption of data of the first part after the authentication of a first combined credential. The encryption and the decryption rely on a cipher key derived from a second combined credential. The first combined credential and the second combined credential are derived from at least a computer signature of the computer connected to the interface and a user credential of a user of the computer connected to the portable storage device.Type: GrantFiled: March 23, 2012Date of Patent: March 25, 2014Assignee: CPO Technologies CorporationInventors: Michael Yuen, Patrick Siu-Ying Hung

Publication number: 20130342688Abstract: A wireless adapter and method for providing a wireless connection to at least one wired security device includes at least one combined data/power physical port to which the wired security device connects. A power supply module receives power from an external power source and a power injector provides power to the combined data/power physical port to thereby power the wired security device. In this way, the wireless adapter supplies both power and data connection at the same physical port/jack of the wired security devices, such as IP security cameras, via an interface cable from the wireless adapter. This configuration has advantages in lowering the manufacturing costs of the cameras and reducing installation costs. Furthermore, the same standard camera can be used for both standard wired connections and wireless connections.Type: ApplicationFiled: June 22, 2012Publication date: December 26, 2013Applicant: SENSORMATIC ELECTRONICS, LLCInventor: Patrick Siu

Publication number: 20110113166Abstract: A USB intermediate device, such as a switch, selectively interconnects computers and console peripherals. The computers are connected via a single USB 3.0 connector. Alternatively, the USB intermediate device selectively shares a peripheral among multiple USB 3.0 connected computers that are in a peer-to-peer session. In yet another alternative, the USB intermediate device combines a charging current from multiple USB 3.0 connected computers and can charge a device with the combined charging current.Type: ApplicationFiled: November 8, 2010Publication date: May 12, 2011Applicant: CPO Technologies CorporationInventors: Patrick Siu-Ying Hung, Toshimi Sakurai, Patrick Wai-Wah Fung

Publication number: 20110022769Abstract: One aspect of the technology is an apparatus with a USB intermediate device such as a USB hub or a USB composite device. The USB intermediate device includes control circuitry that performs translation between USB 2 communications of the multiple downstream USB 2 ports and USB 3 SuperSpeed communications of the upstream USB 3 port. Another USB intermediate device includes control circuitry that modifies apportionment of the USB 3 maximum data rate among the multiple downstream USB 2 ports, such that the multiple downstream USB 2 ports communicate at a collective data rate exceeding a USB 2 maximum data rate of USB High Speed. Another USB intermediate device includes control circuitry that performs translation and modifies apportionment. Other aspects are a system with a host computer, methods, and computer readable media.Type: ApplicationFiled: January 8, 2010Publication date: January 27, 2011Applicant: CPO Technologies CorporationInventors: Patrick Siu-Ying Hung, Toshimi Sakurai

Patent number: 7257545Abstract: A scannable coupon, such as a bar code, is generated on a configurable display of a portable electronic device, such as a personal digital assistant, handheld computer, or mobile telephone. The display has sufficient resolution and contrast to be scanned at a point-of-sale computer for redemption of the coupon. In a further embodiment, generic coupon information is sent to the portable electronic device, which can generate a scannable coupon in any one of several formats. In another embodiment, coupon information is sent in one format and the portable electronic device converts it to another format. In yet a further embodiment, a number of coupons are stored in a data structure according to a redemption characteristic, and may be serially displayed according to user input, such as pushing a step key.Type: GrantFiled: July 26, 2000Date of Patent: August 14, 2007Inventor: Patrick Siu-ying Hung

Patent number: 6765595Abstract: A set of data field characters is displayed in a primary data field if the number of characters in this set of data field characters is equal to or less than the displayable capacity of the primary data field. If the number of characters in the set of data field characters is greater than the displayable capacity of the primary data field, then a proper subset of the set of data field characters is displayed in the primary data field in conjunction with the display of an indicia associated with the primary data field. In response to a user interaction with the indicia, the proper subset of data field characters and at least one additional character from the set of data field characters are displayed in a secondary data field, wherein the proper subset of data field characters and the at least one additional character are simultaneously viewable by the user in the secondary data field.Type: GrantFiled: August 16, 2001Date of Patent: July 20, 2004Assignee: International Business Machines CorporationInventors: Letitia K. Lee, Patrick Siu-Nang See

Patent number: 6749120Abstract: A scanner is provided that can read two-dimensional barcodes from reflective or emissive electronic displays. Illumination, exposure, and contrast can be automatically adjusted according to the type of display and variations in brightness or reflectivity. The scanner includes an imaging camera with high spectral response for reading from color displays. The scanner can also adapt to read barcodes from displays with non-square pixels.Type: GrantFiled: December 11, 2000Date of Patent: June 15, 2004Assignee: CPO Technologies Corp.Inventors: Patrick Siu-ying Hung, James C.
