Abstract: The present invention is directed to methods and compositions for manufacturing a bone graft substitute. A powder compaction process is utilized to generate a shaped product comprised of a granulated bone material, such as demineralized bone matrix. In addition, a processing aid is utilized to facilitate compaction of the granulated bone material and for release of the product from the die.

Abstract: A shaped particle for use in an array of interlocking particles to repair, replace, improve or augment a bone deficiency is provided. The particle is comprised of bone material and, in a preferred embodiment, has six extremities, and the interstitial spaces between the extremities of one particle accept the extremities of an adjacent particle in an array. In a preferred embodiment, the bone material is demineralized bone material. In some embodiments, the particle is suspended in a material that facilitates application of the particle to bone, and the material may contain biological factors that augment bone growth or prevent infection.

Abstract: The present invention relates to a process for charging a battery from an alternating current voltage which provides voltage to the battery in each direction. The charging current is regulated alternatively in a boost and buck mode as a function of an error (AI) between the instant value of the current and an instant value of a supply current following a pre-determined pattern. The activation of the modes of operation is controlled according to the sign of the error of the current (AI). The present invention also relates to a battery charger for implementing the above charging process. The battery charger has two sub-assemblies for current regulation operating respectively in boost and buck modes, a subtractor for determining the error of current, and a common loop for feeding the sub-assemblies and controlling amplifiers for the activation, depending on the sign of the error.
