Patent GB-2382152-A (GB)
Title: Gelatinous heat regulating device for integrated optical devices
Inventor: ANTON MARIANNE
IPC: H01L31/0203
Filed: 2001-11-14
Abstract: An integrated optical package has an integrated optical device 1 which is preferably a silicon-on-insulator device supported on a carrier such as ceramic substrate 2 with a gelatinous material 3 between them to assist in heat conduction. The carrier can include a thermal regulating device such as a heat sink or heating elements 4 for regulating the temperature of the integrated optical device via the gelatinous material. The gelatinous material can include a metallic second phase suspended in the gelatinous material, to improve its thermal conductivity. The maximum dimension of the particles is ideally smaller than the gap between the integrated optical device and the carrier in which the gelatinous material is located, such as in the 5 to 95 percent range of the dimension of the gap. The particles of the metallic second phase can be elongate, in which case they can be aligned with each other such as in a direction extending from the integrated optical device towards the carrier. Alternatively, they can be substantially spherical. Ferromagnetic particles are easier to align by using a magnetic field. The device is made by disposing a closed loop of adhesive, thus forming a well, on one or the other of the integrated optical device or the carrier, placing a gelatinous material into said well, placing the other of the carrier or integrated optical device in contact with the adhesive layer and gelatinous material, and curing the adhesive to form adhesive side walls 5 and secure the integrated optical device to the carrier. The gelatinous material can be thixotropic i.e. the viscosity increases as the shear rate decreases.

Filed: 2001-12-07
Abstract: A frequency synthesizer 100, which includes an output oscillator 17, a difference circuit 16, a reference circuit 11, 12, a feedback circuit 14, 161, 162 and a comparator 13, generates an output signal whose frequency, F<SB>OUT</SB>, is determined by an oscillator input signal. The difference circuit 16 generates a sampled signal having a frequency, <F>F<SB>sif</SB>=F<SB>OUT</SB>-F<SB>OFFSET</SB></F>. The reference circuit 11, 12 generates a reference signal having a frequency F<SB>ref</SB>. The reference circuit includes a reference oscillator 11 for generating a high frequency reference oscillator output signal having a frequency F<SB>1</SB> and a first division circuit 12 for generating a signal having a frequency equal to F<SB>1</SB> divided by R. The feedback circuit generates a feedback signal having a frequency, F<SB>fb</SB>. The feedback signal generating circuit includes a second division circuit having a division factor chosen such that F<SB>sif</SB>/F<SB>fb</SB> is minimized. The comparator 13 compares the reference signal and the feedback signal and generates the oscillator input signal. One of the first and second division circuits is a Fractional-N Divider having a division factor, N.F, greater than 10. If the second division circuit is the Fractional-N Divider, the feedback circuit includes a multiplication circuit 161 for generating a multiplied signal having a frequency equal to X times F<SB>sif</SB>, and the fractional-N Divider generates the feedback signal from the multiplied signal. In the preferred embodiment of the present invention, the first division circuit is the Fractional-N Divider. In one embodiment of the invention, the input to the Fractional N Divider varies over time thereby causing the output oscillator to sweep through a corresponding frequency range.

Title: Method and apparatus for software authentication
Inventor: LEMAY STEVEN G
IPC: G07F17/32
Filed: 2001-08-20
Abstract: A system for authenticating software is disclosed. In one embodiment, the invention is utilized in conjunction with a gaming machine to authenticate the software utilized by the gaming machine or loaded onto the gaming machine. To achieve authentication, one exemplary mode of operation is used to authenticate the contents of a removable media, the removable media being used to perform any desired operation on the gaming machine. Use of a removable media provides means to store large amounts of software on a single media to thereby access and perform numerous tasks including software install, software update, diagnosis, authentication, or configure. Prior to use of the removable media in the gaming machine, an authentication file is created. The authentication file contains a listing of each file on the removable media and an associated hash value calculated with a known hash function. These hash values are calculated and stored in an authentication file when the files on the removable media are known to be trusted. Encryption of the one or more hash values may occur. At a later date when the removable media is used in the gaming machine, a hash value re-calculation is performed on each file to determine the hash value at the time of use. The re-calculated hash values are compared to the decrypted hash values stored in the authentication file on the removable media on a file-by-file basis. If the values match, the removable media authenticates. If the values do not match, the removable media does not authenticate.

IPC: H04W4/24
Filed: 2003-03-26
Abstract: A method for providing communications network access in a public area. The method includes the step 201 of receiving a request to access a communications network from a client. A determination 202 is then made as to whether the request is for access to a first area or a second area of the communications network. The first area can be a local domain of the communications network e.g. a WLAN in an airport or mall. The second area can be the part of the communications network outside the local domain, such as the Internet. In response to receiving a request for access to the first area, access is provided 206 to the services of the first area of the communications network. In response to receiving a request for access to the second area, an authentication process 203 is performed on the client. When the authentication is successful 204, access is provided 205 to the services of the second area of the communications network. The authentication can be performed in accordance with a Web based authentication protocol. The authentication can also be performed in accordance with a basic user registration protocol.
