Abstract: To provide a bicycle retainer through which a suspending state of bicycle can be retained within a passenger room by simple and easy operation and a space for bicycle can be easily restored to passenger space when the bicycle is removed. [Solution] When a bicycle 2 is removed, a hook 47 is first removed from a hooking ring 42a and a rubber string 46 built from a rim side of a wheel 2a is removed from the wheel 2a. Next, the wheel 2a is removed from the space between a first rack member 42 and a second rack member 44, thereby the second rack member 44 is automatically and forcibly folded toward a base member 41 and the first rack member 42 through the forcible power of a spring hinge 43. At that time, although the second rack member 44 collides with the base member 41 or the first rack member 42, collision shock at the time of collision is relieved by a cushion member 45. After the bicycle 2 is removed, based on that a seat 5a of a flip-up seat 5 is moved downward, the retaining space for the bicycle 2 can be restored to passenger's seat.

Title: Latch assembly and tailgate for vehicle
Inventor: SANDLER PHILIP
IPC: E05C3/12
Filed: 2017-09-14
Abstract: A tailgate assembly includes a talegate and latch assembly. The tailgate is moveable between open and closed positions. The latch assembly includes an actuator, a latch, and a stopper. The actuator is operative to move the latch between an unlatched position where the latch allows movement of the tailgate from the closed position, and a latched position where the latch prevents movement of the tailgate from the closed position.

Title: Server-side caching for web user interfaces
Inventor: GEORGE SANTHOSH PHILIP
IPC: G06F15/16
Filed: 2016-07-28
Abstract: The described technology relates to rendering a client-side user interface, such as, for example, display of a web page, using a server-side cache for providing the displayed data. In an example implementation, in response to a user interface (e.g., dashboard with multiple widgets in a web application) being launched on the client device, the server initiates a refresh of the cache for the plurality of widgets; and transmits a first set of data obtained from the cache for widgets in the user interface before the cache is updated in response to the initiated refresh. The first set of data is followed by a second set of data obtained from the cache for at least some of the widgets after the cache is updated in response to the initiated refresh. The client displays the user interface using the second set of data while overwriting, for one or more of the widgets, information previously displayed using the first set of data.
