Abstract: A method for image alignment is provided. The method for image alignment includes the following stages. A first image with a first property from a first sensor is received. A second image with a second property from a second sensor is received. The first property is similar to the second property. The first feature correspondence between the first image and the second image is calculated. A third image with a third property from the first sensor and a fourth image with a fourth property from the second image sensor are received. The third property is different from the fourth property. Image alignment is performed on the third image and the fourth image based on the first feature correspondence between the first image and the second image.

Abstract: A method for high dynamic range imaging is provided. The method includes the following stages. A first image from a first sensor capable of sensing a first spectrum is received. A second image from a second sensor capable of sensing a second spectrum is received. The second spectrum has a higher wavelength range as compared to the first spectrum. A first image feature from the first image and a second image feature from the second image are retrieved. The first and second images are fused by referencing the first image feature and the second image feature to generate a final image.

Abstract: An image calibration method is applied to an image calibration device includes an image receiver and an operation processor. The image calibration method of providing a motion deblur function includes driving a first camera to capture a first image having a first exposure time, driving a second camera disposed adjacent to the first camera to capture a second image having a second exposure time different from and at least partly overlapped with the first exposure time, and fusing a first feature of the first image and a second feature of the second image to generate a fusion image.

Abstract: An optical device is provided. The optical device includes a time-of-flight (TOF) sensor array, a photon conversion thin film, and a light source. The photon conversion thin film is disposed above the time-of-flight sensor array. The light source emits light with a first wavelength towards the photon conversion thin film to be converted into light with a second wavelength received by the time-of-flight sensor array. The second wavelength is longer than the first wavelength.

Abstract: An anti-theft automobile steering wheel lock with an alarm unit includes a stationary base, an insert pin, a helical spring, a locking core, a movable constrict base, an alarm unit and a cover. The locking core can be rotated with a key to let a projecting member move downwards to separate from a fitting hole so that the helical spring extends to push up both the insert pin and the locking core outwards. Meanwhile, the separation of the insert pin away from an insert hole of the telescoping rod enables the movable constrict base moved farther away from the stationary base, unlocking the lock. Reversely, pushing the locking core inwards into the stationary base can lock the lock on the steering wheel, and simultaneously the alarm unit started.

Abstract: An automobile steering wheel lock includes a stationary base, a movable constrict base, an insert pin, a helical spring, and a locking member. A key can unlock the lock by rotating a rotary member of the locking core, with a projecting member of the lock core leaving out of an insert hole of the stationary base so that the helical spring recovers, pushing the insert pin and the lock core outward. Then the insert pin separates from the insert hole of a telescoping rod of the constrict base, and the constrict base is pushed off a section of the steering wheel, thus this lock is unlocked. If the lock core is pushed in the stationary base, with the projecting member fitted in the insert hole of the stationary base, and with the insert pin fitting in the insert hole of the telescoping rod, thus this lock is locked.

Abstract: A burglar alarm lock for steering wheel of cars and particularly to a burglar alarm lock aiming at improving U.S. patent application Ser. Nos. 08/616,338 and 824,781 previously submitted by Applicant to enhance theft-deterrent effect and utilization effectiveness. It has a receiving antenna installed on a lock block adjacent to the window of the driver seat at an elevation slightly higher than the lock body. The antenna is connected to an alarm circuit located in the lock set. Through a remote controller and the antenna, the alarm lock may be activated and the alarm may be released at a long distance. The antenna can attenuate the shield effect and improve signal transmission to enhance control effect at a long distance.

Abstract: A steering wheel lock including a lock body having a bottom open chamber adapted to receive one three-way frame section of a steering wheel of a motor vehicle, a shackle inserted into shackle holes in the lock body and locked by a lock cylinder to firmly secure the lock body to the three-way frame section of the steering wheel, and an alarm system installed in the lock body which is disarmed when the shackle is locked, or triggered to produce an audio alarm signal through a speaker when the shackle is forced out of the locking position.

Abstract: A steering wheel lock with alarm including a shaft connecting two lateral plates of a lock body and fitted with a reset spring, and a speaker base provided with structure for preventing sound muffling being secured at a lower rim of the lock body. By the reset spring, the lateral plates will automatically reset to a released position after the lock is unlocked so as to prevent inadvertent pressing of the lateral plates to actuate the alarm. The speaker base is provided with pins of different heights and ribs thereon for preventing thieves from muffling the alarm sound.
