Abstract: A technique to derive a television color subcarrier frequency signal from a computer video signal is described, A computer generates a computer video signal including a horizontal synchronization signal component, The horizontal synchronization signal component is applied to a subcarrier frequency generator to produce a pixel clock signal and a subcarrier relative phase signal which are applied to a digital encoder. The digital encoder processes the computer video signal, the pixel clock signal, and the subcarrier relative phase signal to generate an analog baseband television signal. The subcarrier frequency generator includes a frequency conversion circuit, a timing source, and a deviation compensator. The conversion circuit receives the horizontal synchronization signal and generates the pixel clock signal. The timing source is used to generate a reference clock signal. The deviation compensator includes a signal comparison circuit to process the pixel clock signal and the reference clock signal and derive a count signal. A ratio counter circuit then processes the count signal and generates a subcarrier relative phase signal, for processing by the digital encoder.

Abstract: A high power factor electronic ballast for operating a high pressure gas discharge lamp comprises a boost converter function (32) and a buck function (34). The boost converter function and the buck function have common components (46). The combination boost-buck converter (30) reduces parts count, as compared to the parts count required for the separate boost and buck circuits of the prior art, by making some components of the single circuit act simultaneously in both the boost and buck functions. The rigid forcing of the ac input current waveform to follow the ac input voltage waveform is relaxed, to give performance priority to the buck function for the common components. Harmonics are allowed to enter the system in moderation in return for a less expensive and more reliable system that does not compromise lamp power control.

Abstract: The method of transmission of a bit pattern involves a two-channel ASK direct conversion receiver with automatic gain control in each channel. The method also uses logic circuitry (ASIC) which recognises binary ones and zeros from cyclic and acyclic sequences of two frequencies (f1,f2). The time windows for both frequencies are the same, and the rate of alternation in the frequency-shift keying is three times that of the rate of alternation of the bit pattern. If either channel is perturbed e.g. by an interfering transmitter, the data transmission can continue via the other channel.

Abstract: The accumulation of lint, debris and other contaminants
in the needle and dial slots of a circular knitting machine
can be significantly reduced by enclosing an annular air
chamber spanning between the cylinder and dial and
delivering a pressurized airstream into the chamber. The
airstream can necessarily escape from the chamber only
upwardly through the spacing between the cylinder and dial
where the airstream serves to blow lint, debris and
contaminants away from the critical knitting elements (e.g.,
needles and sinkers) and prevent the accumulation of such
materials within the cylinder and dial slots. The
conventional need for flushing the cylinder slots can be
reduced or eliminated.

Abstract: When a vehicle is traveling on a descending slope, the gearshift position of an automatic transmission is set to a position selected in accordance with driver's intention of accelerating the vehicle based on accelerator opening. A decision is preferably made as to whether the gearshift position should be set to a low-speed gearshift position where an engine brake can be applied, in accordance with the magnitude comparison between a threshold value and at least one value of gradient of a road and time-dependent change in vehicle speed. The threshold value may be changed to a value that causes the low-speed gearshift position to be easily selected if the frictional resistance of the road surface is judged to be low. Further, the threshold value may be set beforehand which corresponds to the degree of gradient and/or winding of the road, and the threshold value is changed to a value that causes the low-speed gearshift position to be easily selected if the detected operating amount of braking exceeds a predetermined standard value.

Abstract: A method and apparatus to create, distribute, sell and control access to digital documents using secure cryptographic envelopes. An envelope is an aggregation of information parts, where each of the parts to be protected are encrypted with a corresponding part encryption key. These encrypted information parts along with the other information parts become part of the envelope. Each part encryption key is also encrypted with a public key, and these encrypted part encryption keys are also included in the envelope. The envelope also includes a list of parts where each entry in the list has a part name and a secure hash of the named part. The list is then signed with a secret key to generate a signature, which is also included in the envelope. The signature can be verified using a second public key associated with first secret key, and the integrity of any information part in the envelope can be checked by computing a second hash and comparing it with the corresponding hash in the list of parts. Also, the information content of any encrypted part can only be recovered by knowledge of a second secret key corresponding to the public key that was used to encrypt the part encryption keys.
