Abstract: A dynamic footwear midsole has an upper layer and a lower layer that are connected by a group of heel slats and a group of forepart slats, each slat being connected at hinge regions to the upper and lower layers. The slats in each group are arranged in generally paralleling planes with the heel slats and forepart slats being arranged to cause one group to collapse as the other group expands. An arch segment is provided at the midportion of the upper layer is constructed and supported by an arch support structure that enables the upper layer and arch support structure to rock, as a unit, about a pivot region at the lower end of the support structure.

Abstract: A lower chair for supporting an upper chair on which a user sits. The lower chair including a base, a swivel mechanism supported by the base and defining a vertical swivel axis, and a four-bar linkage mounted to the swivel mechanism for rotation about the swivel axis. The four-bar linkage includes a coupler link that moves about a coupler curve. The lower chair also includes a column having a lower end affixed to the coupler link for movement of the lower end along the coupler curve. The column defines a column axis and is adapted to support the upper chair.

Abstract: A chair includes a lower chair and an upper chair. The lower chair includes a tilt-swivel mechanism defining a vertical swivel axis, a yoke, and a column extending between the tilt-swivel mechanism and the yoke. The upper chair is pivotably mounted to the yoke about a horizontal upper chair pivot axis. The upper chair includes a seat adapted to cradle the ischial tuberosities of a user.

Abstract: A seating device includes a base and a seat post extending from the base. The seat post has a first end adjacent the base, a second end opposite the first end, and a longitudinal axis extending between the first end and the second end. The seating device further includes a seat supported by the seat post above the base and a first rocking assembly coupled to the base and the first end of the seat post. The first rocking assembly is operable to angularly displace the seat post relative to the base. The seating device further includes a second rocking assembly coupled to the seat and the second end of the seat post. The second rocking assembly is operable to angularly displace the seat relative to the seat post.

Abstract: Novel sit-stand seating devices, more particularly, to sit-stand seats or stools that can tilt forward to provide balanced support for seated to near-standing postures and methods of their use are disclosed. The sit-stand devices are useful, inter alia, to provide stabilized worker positioning to carry out a task for a range of sitting through standing postures in an environment associated with a task for a worker in need thereof.

Abstract: Bicycle wheels have integral reflective areas to increase visibility of the bicycle. These areas show through portions of the wheel tread, so that the tread protects the reflector material from wear. The reflecting areas are scattered over the wheel and situated at a variety of angles with respect to the plane of the wheel so that reflectors are always situated to reflect light from the sun, a street lamp, or car headlights. A bicycle tire of the conventional sort having a tube and removable outer tire having tread is used. The outer tire has holes formed in it interspersed among the raised areas of tread. Reflecting material in sheets is placed between the outer wheel and the tube. Preferably, the reflecting material is affixed to the outer tire, and is coated with a protective coating.

Abstract: A tilt chair having a foot adapted to be supported by a support surface and a first leg pivotally mounted to the foot. A second leg is pivotally mounted to the first leg. A moveable support member is mounted to the second leg and is adapted to be supported by the support surface. The moveably support member is moveable in a first and second direction toward and away from the foot respectively as the first leg pivots relative to the second leg and as the first leg pivots relative to the foot. In one embodiment, the moveable support member is configured as a wheel. In one embodiment, a lower back member has a lower end pivotally mounted to the first leg and an upper back member pivotally mounted to an upper end of the lower back member. A restraining link is pivotally mounted between the lower back member and the second leg. An upper back link has a lower end pivotally mounted to the first leg and an upper end pivotally mounted to the upper back member.

Abstract: The invention is a system that can be used in conjunction with an enterprise application integration system to monitor and track end-to-end business processes. The invention also provides triggers that can alert individual users, user groups or system administrators in the event of errors or other disruptions. The system automatically generates and forwards messages whenever an error occurs.
