A time-to-contact estimation device for estimating a time to contact of a moving body to an object in surroundings of the moving body, includes: an image sensor provided on the moving body, and continuously capturing time-varying images of the surroundings of the moving body; a brightness change calculation unit calculating brightness changes in pixels between the time-varying images captured one after another; and a time-to-contact calculation unit calculating optimized brightness gradients based on the brightness changes calculated by the brightness change calculation unit, and calculating the time to contact of the moving body to the object based on the optimized brightness gradients.

Described is a robotic system for detecting obstacles reliably with their ranges by a combination of two-dimensional and three-dimensional sensing. In operation, the system receives an image from a monocular video and range depth data from a range sensor of a scene proximate a mobile platform. The image is segmented into multiple object regions of interest and time-to-contact (TTC) value are calculated by estimating motion field and operating on image intensities. A two-dimensional (2D) TTC map is then generated by estimating average TTC values over the multiple object regions of interest. A three-dimensional TTC map is then generated by fusing the range depth data with image. Finally, a range-fused TTC map is generated by averaging the 2D TTC map and the 3D TTC map.

In one embodiment, a method includes obtaining a call from a caller, and determining whether to offer a first callback time to the caller. The first callback time is a future time for a contact between the caller and the call center. The method also includes providing the first callback time to the caller, obtaining a response from the caller, and scheduling the contact at the first callback time if the response indicates that the caller desires a contact at the first callback time. Providing the first callback time to the caller includes soliciting the response from the caller which indicates whether the caller desires the contact at the first callback time.

The invention provides a method and system for prompting objects in a trunk of a taxi, and belongs to the automotive electronic technical field. The method includes the steps that when it is detected that a passenger needs to place the objects into the trunk of the taxi, an information input device located on the trunk obtains passenger information input by the passenger; the information input by the passenger is transmitted to a prompting device located on an instrument table through the information input device; after the prompting device receives and stores the passenger information, an opening command for opening the trunk is transmitted to a vehicle-mounted control unit, and the trunk is controlled by the vehicle-mounted control unit to be opened; when it is detected that the objects are placed into the trunk and the trunk of the taxi is closed, the prompting device transmits the information of the taxi to a mobile phone of the passenger through a mobile phone number of the passenger; when it is detected that the passenger needs to get off the taxi, the prompting device sends a prompting message. By means of the method and system, when the passenger forgets to take away luggage placed in the trunk, a driver can be reminded in time to contact the passenger, and it can be guaranteed that the luggage is finally returned to the passenger who the luggage belongs to.

This invention relates to a method for super-deep removing aromatics in natural gas synthetic oil, in which, a synthetic oil raw material and H enter into a fixed bed reactor at the same time to contact and react with a noble metal catalyst under the following operation conditions temperature: 200-400deg.C total pressure: 2.5~10.0Mpa H branch pressure 2.0-9.0Mpa, H-oil ratio 200~1000N cum / cum, the volume space velocity in liquid: 1.0~1h to get a mixture of oil and gas to be separated and fractionated to get the target product and gas with rich H can be circularly used by a circulating compressor.

The invention aims to provide an extrusion type coating machine so as to solve the problems of slurry layering and metamorphism and effectively improve the coating precision. The extrusion type coating machine provided by the invention comprises a storage tank, a pump body, a coating head, a control unit and a substrate conveying belt. The coating head is arranged over the substrate conveying belt, and is internally provided with a coating cavity, which is equipped with a feed inlet and a discharge port. The discharge port is disposed at the bottom of the coating cavity. The storage tank, the pump body and the feed inlet of the coating cavity are connected in order through a pipeline. The coating cavity is internally equipped with a pressure sensor. The pressure sensor and the pump body are connected to the control unit. The extrusion type coating machine provided by the invention changes the feeding mode and coating mode of traditional coating machines, the slurry can be always in a flow state, and has very short time to contact the air during coating, so that no packing effect can be generated, and a coating roll, a rubber roll or other parts are not needed. Therefore, the problems of slurry layering and metamorphism are solved, and the coating precision is effectively improved.

Technologies are disclosed for determining a best time to contact a party over a plurality of contact periods of time to achieve at least one of a desired outcome and a desired result. In various embodiments, the party has multiple contact types that can be utilized to contact the party. Accordingly, an optimal contact type for the party for each contact period is selected that identifies the contact type with a probability having the highest likelihood of achieving at least one of the desired outcome and the desired result by utilizing the contact type to contact the party during the contact period. A best time to contact the party is then identified as one of the contact periods based on the optimal contact types selected for the party for each contact period and associated probabilities.

This invention relates to a method for super-deep removing aromatics in two steps from natural gas synthetic oil, in which, a natural gas synthetic oil raw material and H enter into a first fixed bed reactor at the same time to contact and react with a hydrofining catalyst, the reacted substance from the first reactor enters into a second fixed bed reactor directly to contact and react with an aromatic saturated catalyst to get a gas-oil mixture to be separated and fractionated to get the target product, the gas with rich H is used circularly by a circulating compressor.
