  • Patent number: 11713448
    Abstract: Methods for producing hepatocytes from pluripotent human stem cells are disclosed herein. The stem cells are plated on a cell culture substrate comprising two laminins. The stem cells are then exposed to different cell culture mediums to induce differentiation. The resulting hepatocytes have higher metabolic capacity compared to hepatocytes cultured on different substrates.

  • Publication number: 20230135425
    Abstract: Techniques for determining and displaying error messages including a cause of an error generated because two types are not members of the same nest are disclosed. The system detects, at runtime, an instruction in a first type that attempts to access a private member of a second type. The system evaluates one or more nestmate criteria to determine whether the first type and the second type are within a same nest. A nest host corresponding to the nest specifies each nest member of the nest, and each nest member specifies an association with the nest. Responsive to determining that a particular nestmate criterion is not met, the system determines that the first type and the second type are not within the same nest and records or displays data identifying the particular nestmate criterion that has not been met, and throws an access error.

  • Patent number: 11368071
    Abstract: An electric drive includes a motor and a transmission for transferring torque from the motor to a tool. The transmission includes a plurality of planetary rollers which are driven by a rotary shaft of the motor, and an output ring which is connectable to the tool, and which is driven by the planetary rollers. The transmission further includes a roller casing which is secured to a housing of the motor, and which supports parallel planetary shafts upon which the planetary rollers are mounted for rotation relative to the roller casing, and a bearing having an inner race which engages the roller casing, and an outer race which engages the inner periphery of the output ring.

  • Patent number: 11198650
    Abstract: A sheet 100 of water-soluble material such as polyvinyl alcohol comprises a plurality of individual, sealed pockets 110, each containing concrete admixture. The sheet is cut to size and attached to the interior of a formwork structure 200 with, for example, PVA glue. After concrete is poured into the formwork, covering the sheet 100, the sheet dissolves, releasing the admixture onto the surface of the concrete as it sets. In another arrangement, a sealed container 300 formed from a water-soluble material contains concrete admixture. The external wall of the container has a plurality of regions 320 where a thickness of the wall is reduced. The container is attached to interior walls of a formwork structure 200 or to reinforcing bars inside a formwork structure. After concrete is poured into the formwork, submerging the container, the container dissolves, with the thinner regions dissolving sooner, releasing the admixture into the concrete.

  • Patent number: 9204770
    Abstract: A cleaner head for a cleaning appliance includes a housing having an upper surface and an underneath surface in which at least on suction opening is formed. The underneath surface has opposing side edges each having a first part which lies adjacent the suction opening or openings and forms a sharply-defined edge with the upper surface and an upwardly curved second part which is located rearwardly of the suction opening or openings. This arrangement is advantageously used in vacuum cleaners or other cleaning appliances in which a ball-type support allows an increased level of steerability involving lateral movement of the cleaner head across the surface to be cleaned. The upwardly curved side edges of the underneath surface of the cleaner head reduce the amount of effort required to achieve the steering by presenting a smoothly curved surface to the carpet or other floor covering.

  • Patent number: 9127802
    Abstract: The present invention provides a pipeline pig (10) comprising an elongate body (12) and annular front and rear supports (26,30) projecting radially from the body (12). Each support (26,30) has an upstream side and a downstream side, with the front support (26) including at least one first fluid passage (18) permitting fluid flow from the upstream side to the downstream side. and the rear support (30) including at least one second fluid passage (22) permitting fluid flow from the upstream side to the downstream side. The pig further comprises a launch valve (50) adapted to move from an open position to a closed position to close the at least one first fluid passage (18), and a control means adapted to control the closing of the launch valve (50). A launch trap for launching pigs into a pipeline is also provided.

  • Patent number: 9056041
    Abstract: The present invention is a device that is configured to secure a patient's head against the force of gravity during surgery (or other medical procedures) while the patient is in an upright, sideways (tilted to the side), or upside down position, or in any other non-horizontal position, for any duration of time. The device is designed to safely secure a patient's head or neck to prevent potential injury to the patient who is unconscious and unable to protect themselves through reflex reactions or otherwise. Without the device, a patient's head would drop forward or sideways by force of gravity, and if it remained in the dropped position, the patient's neck, shoulder, and/or spine regions could suffer temporary or permanent soreness, strain, and/or injury. This device is designed to reduce or eliminate such soreness or injury.

  • Patent number: 8966708
    Abstract: A surface-treating appliance includes a main body, a surface-treating head and a support assembly. The support assembly is moveable out of a supporting position in which it supports the main body by a user performing a plurality of steps—for example, by depressing a pedal, then tilting the main body by pulling the handle. This arrangement reduces the likelihood of accidental release of the support assembly from its supporting position. For example, if the user depresses the pedal alone, or only pulls on the handle, the support assembly remains in its supporting position.

  • Patent number: 8932314
    Abstract: Described and illustrated herein is an exemplary lancing device. The lancing device includes a first housing, second housing, movable member, lancet, and lancet depth adjustment member. The lancet depth adjustment member is captured by both the first and second housings so that the lancet depth adjustment member is rotatable relative to both housings to provide for a plurality of stop surfaces to the movable member. Other exemplary embodiments are also described.

  • Patent number: 8769765
    Abstract: A surface treating appliance, such as a vacuum cleaner, includes a device generating a flow of fluid in the form of a motor and fan, housed in a main body. A hose and wand assembly, a surface treating head and a rotary change over valve are also provided. The valve is selectively rotatable so as to allow fluid flow from either the surface-treating head or the hose. A support assembly is moveable between a supporting position, in which it supports the main body, and a retracted position. The change over valve and support assembly are arranged so that motion of the support assembly between the supporting and retracted positions induces rotary motion of the change over valve.
