摘要： A fixed lens camera comprises a fixed focus lens, an infrared filter, and an optical low pass filter, all disposed in succession within a housing, coaxial with an optical axis. Light from a target passes through an aperture in the housing, and then through the lenses and filters. An image sensor receives the filtered light, and outputs a two-dimensional array signal of corresponding voltages proportional to the incident light striking each sensing element. The voltage signal from the image sensor is filtered using a high pass filter, and the high frequency components of the signal are measured to determine the relative focus of the light from the target. The signal measurement is displayed on a bar LCD to enable focusing of the lens by moving the camera along the optical axis while observing the LCD output.

摘要： A system and method for conserving power within a backup battery device comprises a main battery for generating a main operating voltage and a secondary operating voltage, a switching device for connecting the main operating voltage to a secondary power bus which powers a memory device, and a power manager for sensing whenever the main battery drops to a first threshold voltage, whereupon the power manager connects the secondary operating voltage to the secondary power bus if the memory device contains data, and disconnects the main operating voltage from the secondary power bus. The backup battery generates the secondary operating voltage whenever the power manager senses that the main battery has reached a second threshold voltage.

摘要： A power supply provides a voltage to a digital camera. If the power supply voltage falls below a predetermined threshold, a voltage sensor generates a signal to a power manager. In response, the power manager configures the camera into a lower power consumption state. As the power source weakens further, the power manager continues to place the camera into a lower and lower power consumption state, until the power source is exhausted. The method of the present invention preferably comprises the steps of monitoring the power source's voltage, generating a signal if that voltage falls below a pre-determined threshold, and reducing the camera's power consumption in response to the signal.

摘要： The invention comprises a battery coupled to a power bus, an external power connector coupled to the power bus for receiving an external power plug, and two switching devices for disconnecting the battery from the power bus when the external power plug is coupled to the connector. The battery supplies power to the camera unless the external power plug is coupled to the connector. Upon coupling of the external power plug to the connector, the two switching devices, which are positioned in series between the negative terminal of the battery and the system ground, are opened. The opening of the two switching devices disconnects the battery from the power bus and connector to prevent damage which could be caused by applying an externally supplied voltage from the external power plug across the positive and negative terminals of the battery.

摘要： A method and system provides for increasing the throughput of serial data in a computer system when a data packet is of unknown length. The method and system includes initializing a first count register to count a length field of the data packet, the length field including a value indication of the length of the data packet. The method and system further includes storing a count for a minimum data portion in a second count register and receiving the data packet from a serial device of the computer system. The method and system further provides for transferring the length value to the RAM of the computer system and loading the count for the minimum data portion into the first count register to provide primary chaining of the first count register to the second count register. The method and system finally provides for comparing a minimum data packet length to the length value in the RAM to determine whether to utilize secondary chaining of the first count register with the second count register.

摘要： A fixed-focus camera having a retractable close-up lens, fixed-focus lens, infrared filter, and optical low-pass filter disposed along an optical axis within a housing. The close-up lens is switchable between a close-up position coaxial with the optical axis and a far position not coaxial with the optical axis. Light received from a target passes through an aperture in the housing and then through the lenses and filters. An image sensor receives the filtered light and outputs a two-dimensional array signal of corresponding voltages proportional to the energy of light striking each sensing element. The voltage signal from the image sensor is filtered using a high-pass filter and the high-frequency components of the signal are measured to determine a relative focal value for the light received from the target. The close-up lens is retracted for calculating a far-position focal value and then engaged for calculating a close-up position focal value, and the calculated focal values are compared to empirically-derived constant values to determine which lens position will produce a better-focused image.

摘要： An orientation sensor generates a left orientation signal and a right orientation signal to indicate whether a camera is in an upright orientation, a left orientation, a right orientation, or an inverted orientation. A setting unit retrieves the left and right orientation signals and light intensity signals corresponding to image measurement zones. Based upon the values of the left and right orientation signals, the setting unit uses different weighted combinations of the light intensity signals to determine optimum exposure and focus settings. The orientation sensor includes a first tube and a second tube that each contain an indicating object. The indicating object within each tube selectively provides two orientation signals based upon the camera's orientation relative to an image, thereby changing an orientation signal from a binary "0" signal to a binary "1" signal.
