This week, the US patent office issued 6,769 patents. Each patent adds a little something new to the human knowledge base. As we cannot list all five thousand, the PatentYogi team has selected the six most interesting patents.
The hybrid propulsion spacecraft may have a high thrust (HT) engine, such as a chemically powered engine and a low thrust (LT) engine such as a solar electric propulsion engine.It works by determining an optimal trajectory with low fuel/propellant use and fast flight times.
The optimal trajectory includes an optimal LT trajectory portion selected from a stable manifold trajectory and an optimal HT trajectory selected from a manifold of bridge orbit arcs.
It exploits the fact that the spacecraft will almost need no fuel to go into orbit about L2, as the spacecraft will be ballistically captured in a weak stability boundary region about L2O.
Using this technique can reduce the number of maneuvers to be performed while getting from LEO to L2O by as much as 20 percent with a flight time of as less as six to seven days.
NASA helps athletes “get in the zone” quickly
It is well known in the field of performance psychology that the peak performance of a task, such as, for example, putting in golf, requires an optimal physiological state, which is colloquially referred to as “being in the zone.”
NASA’s patented technology includes a portable device (such as a head-mounted display) that provides performance-enhancing biofeedback training to the trainee. The novelty of the solution is that it tightly embeds the biofeedback training in the actual task whose performance is to be improved. Further, the training is operational in real-time, precisely at the moment when a task or exercise, such as an athletic or military maneuver, is required to be performed. Therefore, the players can use the technology during practice before the match to get in the zone.
The patented technology can help players accomplish various tasks including putting in golf, foul shooting in basketball, serving in tennis, marksmanship in archery or on a gunnery range, shooting pool or even throwing darts.
Microsoft has invented a Smart Ring. According to Microsoft, the smart ring can act as a universal input device that will work with TVs, desktop computers, laptops, smart phones, tablets and even other wearable devices like glasses, wrist bands, and watches.
The smart ring includes a flexion sensor to detect a pose of the finger. This enables the smart ring to interpret movement of the finger and the fingertip. The smart ring wirelessly transmits information related to the pose and movement of the finger to control any companion device.
Thereby, the smart ring allows a user to use her finger to control the companion device.
It will be a big relief for users if a single device can be used to control all devices
Disney patents animated books
Disney’s patented books include a number of physical pages. Further, one or more projectors are embedded in the rear cover of the book. The projectors project light based on the page opened by the user.
Users can also interact with the content using voice or touch based inputs. For example, the elf is projected by the projector on a page of the book. When user touches the page, the projector shifts the projection of elf accordingly.
