A tilt sensor can measure the tilting in often two axes of a reference plane in two axes. In contrast, a full motion would use at least three axes and often additional sensors. One way to measure tilt angle with reference to the earths ground plane, is to use an accelerometer. Typical applications can be found in the industry and in game controllers.

Handheld rangefinder operable to determine hold-over ballistic information

ActiveUS8081298B1Facilitates accurate firearm useOptical rangefindersSighting devicesComputer scienceTime-Consuming

A handheld rangefinder device operable to determine ballistic hold-over information is disclosed. The rangefinder device generally includes a range sensor operable to determine a range to a target, a memory storing a database of ranges and corresponding hold-over values for a default sight-in distance, and a computing element, coupled with the range sensor and the memory. The computing element may calculate an adjusted hold-over value based on the range and an actual sight-in distance. Additionally, a tilt sensor may be included to provide information for calculating an angle-adjusted hold-over value. Such a configuration facilitates accurate firearm use by providing ranges and hold-over values without requiring time-consuming and manual user calculations.

Walking assistance moving vehicle

InactiveUS20150066242A1Carriage/perambulator accessoriesDigital data processing detailsMobile vehicleDistance sensors

A walking assistance moving vehicle includes a walking assistance moving vehicle main body with wheels, a distance sensor, an inclination sensor, and a controller. The distance sensor senses distance between the walking assistance moving vehicle main body and an object ahead of the walking assistance moving vehicle main body. The inclination sensor senses inclination of the walking assistance moving vehicle main body. The controller distinguishes between a first state in which the walking assistance moving vehicle moves on a sloped ground and a second state in which at least one of the wheels is off a ground based on the distance sensed by the distance sensor and the inclination sensed by the inclination sensor. The controller further controls the walking assistance moving vehicle main body according to a result of distinguishing between the first state and the second state.

Method and device for monitoring deep scarification operation quality

InactiveCN110352650AImprove effectivenessRealize the bindingAgricultural machinesParticular environment based servicesScarificationMonitoring system

The invention discloses a method and device for monitoring deep scarification operation quality. The device comprises a deep scarification sensor and a control mainframe; the deep scarification sensoris used for collecting deep scarification operation state and parameter related data and comprises a first tilt sensor and a second tilt sensor, the first tilt sensor is mounted on a tractor and deepscarification machine traction rod, and the second tilt sensor is mounted on a tractor body; the control mainframe comprises a master control unit and a transmission module, and the master control unit is used for processing data collected pairwise to conveniently acquire real-time tilling depth values and operation state information. By the method and the device for monitoring deep scarificationoperation quality, technical problems of operation depth measurement, effective operation area statistics and operation vehicle Beidou positioning in supervision of deep scarification operation quality of agricultural machinery are solved, and accordingly the defect of poor performance in monitoring of tilling depth and area of a deep scarification machine in the prior art is overcome. The methodand the device are applicable to construction of an agricultural informationized monitoring system, and agricultural production efficiency is improved.

Vehicle-mounted accident informing system

ActiveCN103824428AImprove accuracyImprove timelinessAlarmsCommunication unitEngineering

The invention discloses a vehicle-mounted accident informing system, which comprises mobile intelligent electronic equipment and vehicle-mounted accident monitoring equipment arranged on a car, wherein the vehicle-mounted accident monitoring equipment comprises a vibration sensor, an infrared sensor, an inclination sensor, a processing module, a Bluetooth module and a GPS (Global Positioning System) module; the mobile intelligent electronic equipment comprises a processing unit, a Bluetooth unit and a remote wireless communication unit. When signals of the three sensors are greater than a preset threshold value, a phone call is made or a short massage is sent to a preset phone number through the system so as to inform the occurrence and place of an accident. By adopting the system, relevant departments or relatives and friends can be informed of the place of the accident in time, so that the death rate and disability rate in car accidents are lowered to the maximum extent, and the timelines of rescue is ensured. The invention further relates to a car accident informing method.
