I do like this:

class ApplicationController < AC::Base
  after_filter :clear_attached_unit # UPDATED

  protected
  def clear_attached_unit
    session[:attached_unit_path] = nil unless keep_attached_unit_path?
  end

  def keep_attached_unit_path? # UPDATED
    @keep_attached_unit_path   
  end                           
end


class UnitController < ApplicationController
  before_filter :attach_unit, :only => [:show]

  protected
  def attach_unit
    session[:attached_unit_path] = request.url if request.get? && !request.xhr?
  end
end

class SessionsController < Devise::SessionsController
  before_filter :keep_attached_unit_path! # UPDATED

  protected
  def keep_attached_unit_path! # UPDATED
    @keep_attached_unit_path = true
  end

  def after_sign_in_path_for(resource_or_scope)
    if resource_or_scope.is_a?(User) && session[:attached_unit_path].present?
      session[:attached_unit_path]
    else
      super
    end
  end 
end

And extract this to module.
