Abstract: The present invention extends to methods, systems, and computing system program products for iteratively calculating autocorrelation function for streamed data in real time by iteratively calculating one or more components of autocorrelation function. Embodiments of the invention include iteratively calculating one or more components of autocorrelation function at a specified range of lags in an adjusted computation window based on the one or more components of the autocorrelation function at the specified range of lags calculated for a previous computation window and then calculating the autocorrelation function at the specified range of lags using the iteratively calculated components. Iteratively calculating autocorrelation function avoids visiting all data elements in the adjusted computation window and performing redundant computations thereby increasing calculation efficiency, saving computing resources and reducing computing system's power consumption.

Abstract: The present invention extends to methods, systems, and computing system program products for incrementally calculating correlation for Big Data or streamed data. Embodiments of the invention include incrementally calculating one or more components of a correlation for two modified computation subsets based on one or more components calculated for two previous computation subsets and then calculating the correlation based on the incrementally calculated components. Incrementally calculating the components of a correlation avoids visiting all pairs of data elements in the two modified computation subsets and performing redundant computations thereby increasing calculation efficiency, saving computing resources and reducing computing system's power consumption.

Abstract: A method of protecting a computing device is provided including detachably connecting a leading edge of a base portion of the computing device to one or more device receiving members of a first portion of a case. The trailing edge of the base portion is secured to the first portion of the case. The first portion of the case may substantially envelope the base portion of the computing device and a plurality of perimetral fastening members may be detachably connected to a second portion of the case. The perimetral fastening members may detachably connect to perimetral edges of a screen portion of the computing device. A protective shell may be formed around the computing device by pivoting adjoining edges of the first and second portions of the case about a linking pliable member in communication with the trailing edge of the computing device.

Abstract: Eating utensils disclosed herein provide desirable aspects of a fork and chopsticks and also provide improved dexterity that enables functionality not possible with either a fork or chopsticks. The eating utensils allow a user to grasp, shovel, and pierce food as well as scoop under food from one side or both sides and to cut food with a side edge, all with a single utensil operated with one hand. Because of the unique way the eating utensil is held and operated, it feels natural to both traditional fork users and chopsticks users.

The tow bar assembly is arranged in front of the single-cross folding assembly. The bottom frame folding assembly is arranged below the single-cross folding assembly. The single-cross folding assembly has a cross inner frame, a cross outer frame, a front wheel supporting tube and a rear wheel supporting tube. The cross inner frame includes an upper cross inner frame part (is in a backward U shape) and first lower cross tubes. The rear ends of the left and right sides of the upper cross inner frame part include the two first lower cross tubes front ends are hinged with the front ends of the first lower cross tubes and the rear ends are hinged with the lower end of the rear wheel supporting tube.

Abstract: A translational collapsible wagon includes a frame assembly, a tow bar assembly and wheels. The frame assembly includes a bottom frame, a front frame, a rear frame and collapsible side frames arranged on the left side and the right side of the bottom frame. Each side frame includes coplanar X-shaped cross tube assemblies. Each coplanar X-shaped cross tube assembly includes a first oblique tube, two second oblique tubes and a hollow seat. A strip opening is formed in the middle of the hollow seat in the front-back direction. Tube connectors are oppositely arranged at the front end and the rear end of the hollow seat in the vertical direction respectively. The first oblique tube penetrates through the strip opening and is hinged to the middle of the strip opening at the center through a hinge shaft. The two second oblique tubes are mounted in the tube connectors at the front end and the rear end of the hollow seat respectively and arranged in parallel and intersect with the first oblique in an X shape.

Abstract: A pole saw apparatus includes a saw blade, a pole, and a tubular adapter connecting the saw blade to the pole. The adapter includes an obround blade-receiving end that stably telescopingly engage sides of the blade-receiving end, with bolts fixing the blade on the adapter. The adapter also includes a pole-engaging end that is cylindrically shaped to telescopingly engage the anchoring end of the pole. A friction clamp includes a transverse shaft extending through the pole, the shaft being shaped to slide into longitudinal slots in the pole-engaging end of the adapter and then rotate into circumferential slots where it is not longitudinally removable. A rotatable cam handle on the clamp is manipulated to create circumferential friction to hold (or release) the adapter on the pole. The blade, adapter and pole align along a common centerline for robust and balanced use.

Abstract: Bags or carriers are provided that can be transformed into protective vests and used as body armor and ballistic shields. The carriers can be assembled in a first arrangement that enables individuals to store and transport items. The carriers can quickly and easily be converted to or deployed in a second arrangement which enables the individuals to wear the carriers as protective vests. One or more shoulder straps can be detached from the carriers for use as tourniquets, doorway securing structures, and tools for dragging injured victims.

Abstract: The present invention extends to methods, systems, and computing system program products for decrementally calculating autocorrelation for Big Data. Embodiments of the invention include decrementally calculating one or more components of autocorrelation at a specified lag for an adjusted computation window based on the one or more components of an autocorrelation at the specified lag calculated for a previous computation window and then calculating the autocorrelation at the specified lag based on one or more of the decrementally calculated components. Decrementally calculating autocorrelation avoids visiting all data elements in the adjusted computation window and performing redundant computations thereby increasing calculation efficiency, saving computing resources and reducing computing system's power consumption.

Abstract: A seat adapter removably mounts a child seat to a wagon having two opposing walls and an interposed connecting wall, and includes two latch components that mount to the wagon's opposing walls. In some embodiments, the seat adapter includes a cross-member extending between the latch components so that the cross-member provides structural integrity to the wagon if the connecting wall is displaced from its upright use position. In some embodiments, the seat adapter and the child seat can be mounted to the wagon for use with the connecting wall in its upright use position, and in some embodiments the seat adapter and the child seat can be mounted to the wagon for use whether the connecting wall is in its upright use position or its displaced position, with no mechanical interference between any part of the wagon and any part of the adapter or the child seat mounted to it.

Abstract: Aspects of the present disclosure are directed to a glove, having a palm-side base material, a backhand-side base material attached to the palm-side base material, and at least one repositionable finger covering operable to selectively cover a finger. A respective repositionable finger covering of the at least one repositionable finger covering is positionable in a finger-covering configuration, in which a finger is not exposed from the glove, and is positionable in a finger-exposed configuration, in which the finger is exposed from the glove while the glove is on a user's hand. When in the finger-covering configuration, a portion of the respective repositionable finger covering is overlapped by the palm-side base material such that the portion of the respective repositionable finger covering is arrangable underneath the palm-side base material.
