Abstract: The invention describes particles having a polypeptide shell. The polypeptide shell comprises at least one immunomodulatory polypeptide. Particles may be ultrasound-responsive particles, providing the ability to administer particles trandermally, or deliver particles to selected sites by use of ultrasound. Administration of the particles generates immunologic response to the polypeptide in the shell of the particle. The particles are therefore useful in methods of immunotherapy.

Abstract: The invention describes vaccine compositions containing particles having a polypeptide shell and a water-immiscible core. The polypeptide shell may comprise one or more pathogenic antigen proteins and/or one or more adjuvant polypeptides. Administration of the composition generates an immune response to the polypeptide contained in the shell. Adjuvant may be comprised in the water-immiscible core of the particle. The particles are therefore useful in methods of vaccination.

Abstract: A collaborative robot employs low ratio drives for three or more axes of movement, such as three primary axes. An arm assembly may be mounted to a support for movement along a vertical linear axis, and the arm assembly may include first and second arm links that are each rotatable about vertical axes, e.g., such that the arm links move in a horizontal plane. Low ratio drives may be used for movement along the vertical linear axis and the rotary axes for the first and second arm links. Feedforward and feedback control may be employed to control the movement of the arm assembly and arm links, and feedback torque components may be limited to 25% or less of the maximum drive torque.

Abstract: A robotic system including at least one support that supports a carriage for movement. The support may include a drive surface that is a “net shape” surface, i.e., is formed without machining. The carriage may have a traction drive that engages with the drive surface to move the carriage relative to the support. The traction drive may allow for slip at the drive surface. A bearing arrangement used to support the carriage on the support may require mainly radial forces be exerted on roller bearing elements on the carriage. A machine vision system and/or force control techniques may be used to control movement of the carriage and/or other portions of the robotic system.

Abstract: A variable reluctance motor and methods for control. The motor may include N motor phases, where N equals three or more. Each motor phase may include a coil to generate a magnetic flux, a stator and a rotor. A flux-carrying element for the rotor and/or stator may be made entirely of SMC. The stators and rotors of the N motor phases may be arranged relative to each other so that when the stator and rotor teeth of a selected phase are aligned, the stator and rotor teeth in each of the other motor phases are offset from each other, e.g., by an integer multiple of 1/N of a pitch of the stator or rotor teeth. A fill factor of the coil relative to the space in which it is housed may be at least 60%, and up to 90% or more. The stator and rotor flux-carrying elements together may include at most three separable parts.
