  • Patent number: 11011275
    Abstract: A system and method of diagnosing gastrointestinal neoplasm or pathologies in an endoscopy system including an endoscopy system display for displaying an image enhanced endoscopy (IEE) image. The method includes randomly generating training image samples with or without cancer region(s) by an adversarial network (AN) including collecting endoscopic training images (T1) and automatically generating a realistic IEE image as a new training image sample (T2) using a generator network in the AN from a generated segmentation map; using a prediction network (L1PN) to learn a level 1 prediction result being a cancerous probability of an IEE image from the collected T1 and T2; using a prediction network (L2PN) to learn a level 2 prediction result being detected cancerous region(s) of an IEE image; and predicting the level 1 result and the level 2 result for an IEE image using the L1PN and the L2PN and without using the AN.

  • Patent number: 8240323
    Abstract: A rain shielding device for an automobile includes an umbrella holder, an umbrella cloth, and a power accumulator. The umbrella holder includes a first edge column mounted on a vehicle door, a second edge column mounted on a vehicle body, a plurality of main umbrella sticks between the first edge column and the second edge column, and two interlock members. The umbrella cloth is covered on the umbrella holder. The power accumulator includes a movable member, a plurality of auxiliary umbrella sticks, and an energy-storing member. The interlock members move the movable member when the vehicle door opens, and then the movable member interacts with the auxiliary umbrella sticks to push the main umbrella sticks and umbrella cloth unfolding. The energy-storing member stores energy when the umbrella cloth unfolds and releases energy when the vehicle door is closed; thus provides an auxiliary force when the umbrella cloth folds/unfolds.

  • Patent number: 8165325
    Abstract: An automotive virtual surround audio system is implemented in an automobile to receive left- and right-channel audio sources. A synthesizer receives the left- and right-channel audio sources to extend the sources into temporary rear-left and rear-right audio sources. A weighting device receives the left- and right-channel audio sources to perform a weighting operation and produce temporary front-left and front-right audio sources. A first filter receives the temporary front-left and front-right audio sources to perform a filtering operation and produce virtual front-left and front-right audio sources. A second filter receives the temporary rear-left and rear-right audio sources to perform a filtering operation and produce virtual rear-left and rear-right audio sources.

  • Patent number: 8031883
    Abstract: A crosstalk cancellation system for preserving quality of sound and the parameter determining method thereof. The system can cancel a two-channel audio signal without compensating a frequency response of an ipsilateral HRTF. The method includes providing an audio signal input device for inputting the two-channel audio signal, modeling a relation between parameters of the crosstalk cancellation system and a head related transfer function (HRTF) to thereby obtain an output transfer impulse response, setting contralateral parts of the output transfer impulse response approximate to zero, setting ipsilateral parts of the output transfer impulse response equal to a delay of ipsilateral head related impulse responses (HRIRs) corresponding to the HRTF, and performing an inverse operation to compute the parameters of the crosstalk cancellation system.

  • Patent number: 7316299
    Abstract: A brake device for a chain saw is provided, wherein a driving shaft, which passes through a brake block, a torsion spring, a driving block and a chain wheel, is assembled with a driven gear, and two ends of the torsion spring are respectively fixed to the brake block and the driving block. The driven gear is loosely fit to the brake block, and the chain wheel is fixed to the driving shaft. When the driven gear is driven to rotate, the brake block, the driving shaft and the chain wheel are brought to rotate synchronously. When a force is applied to the brake block via a brake pin, the torsion spring will deform and separate from the driving block so that the driving block fails to transmit a driving force to the brake block, and thereby the braking effect is achieved.

  • Patent number: 7114479
    Abstract: An engine starting device includes a starting unit, a clutch unit and a transmission unit, all of the three units being installed on the same axle. The starting unit and the clutch unit are connected with each other by friction therebetween and the friction is applied only when the starting unit is operated in desired direction so that the starting unit and the clutch unit are co-rotated. The clutch unit is connected to the transmission unit so that the power can be directly transferred to the transmission unit. The device employs the pressure of the engine to compress the coil spring which generates a force to accelerate the speed of the engine such that the user can easily start the engine.
